what are the conditions under which a Trust may face the solution and what happens to the assets of the trust upon its dissolution ​

Answers

Answer 1

A trust may be dissolved under a variety of circumstances, including the completion of its purpose, the agreement of all parties involved, or a court order. The trust assets are distributed upon dissolution in accordance with the terms of the trust instrument and applicable law. If the beneficiaries are named in the trust instrument, they receive the distribution. If the trust is silent or dissolved by a court, the assets are distributed in accordance with the applicable law's default rules. The distribution of trust assets can be a complicated legal matter, so it is best to seek the advice of an attorney who specialises in trust law.

Answer 2

When a trust is dissolved, the assets of the trust are distributed according to the terms of the trust document. Typically, the trustee will distribute the assets to the beneficiaries or to their designated heirs.

What are the conditions by which trust face dissolution ?

A trust may face dissolution under certain conditions, including:

Termination date: A trust may be established with a specific termination date. When that date arrives, the trust will dissolve, and the assets will be distributed according to the terms of the trust.

Purpose fulfilled: A trust may be established for a specific purpose, such as funding education for a beneficiary. Once the purpose of the trust is fulfilled, the trust may dissolve.

Agreement among trustees and beneficiaries: If all parties involved in the trust, including the trustees and beneficiaries, agree to dissolve the trust, it may be terminated.

Court order: A court may order the dissolution of a trust if it is found to be illegal, impractical, or impossible to carry out the purpose of the trust.

When a trust is dissolved, the assets of the trust are distributed according to the terms of the trust document.

Typically, the trustee will distribute the assets to the beneficiaries or to their designated heirs. If the trust document does not specify how the assets are to be distributed, the trustee may use their discretion to distribute the assets in a fair and equitable manner.

a 30.00-ml sample of 0.125 m hcooh is being titrated with 0.175 m naoh. what is the ph after 21.4 ml of naoh has been added? ka of hcooh

Answers

The pH of the solution after 21.4 mL of NaOH has been added is 3.75.

What is the pH of the solution?

HCOOH (formic acid) is a weak acid, so we can use the Henderson-Hasselbalch equation to calculate the pH of the solution at any point during the titration.

The Henderson-Hasselbalch equation is:

pH = pKa + log([A-]/[HA])

where;

pKa is the acid dissociation constant, [A-] is the concentration of the conjugate base (in this case, HCOO-), and [HA] is the concentration of the acid (in this case, HCOOH).

At the beginning of the titration, before any NaOH has been added, the solution contains only HCOOH and its conjugate base, HCOO-.

The concentration of HCOOH is 0.125 M, and the concentration of HCOO- is 0.

We can calculate the pH using the Henderson-Hasselbalch equation:

pH = pKa + log([A-]/[HA])

pH = -log(1.8 x 10⁻⁴) + log(0/0.125)

pH = 2.74

At the equivalence point, all of the HCOOH has been converted to HCOO- by the addition of NaOH, so the pH will be determined by the concentration of the resulting salt. Since HCOO- is the conjugate base of a weak acid, it will undergo hydrolysis to a small extent, producing OH- ions and raising the pH.

However, we are not at the equivalence point yet.

To find the pH after 21.4 ml of NaOH has been added, we need to first calculate how many moles of NaOH have been added. We know the concentration of the NaOH solution (0.175 M) and the volume that has been added (21.4 mL = 0.0214 L), so we can calculate the number of moles of NaOH:

moles NaOH = concentration x volume

moles NaOH = 0.175 M x 0.0214 L

moles NaOH = 0.003745

Since NaOH reacts with HCOOH in a 1:1 ratio, we know that 0.003745 moles of HCOOH have been neutralized.

This means that there are 0.125 - 0.003745 = 0.121255 moles of HCOOH remaining in the solution.

We also know that 21.4 mL of NaOH has been added to 30.00 mL of HCOOH, so the total volume of the solution is now 51.4 mL.

We can use the moles of HCOOH and the total volume to calculate the concentration of HCOOH:

concentration = moles/volume

concentration = 0.121255/0.0514

concentration = 2.357 M

We can use this concentration and the concentration of the conjugate base (which is equal to the number of moles of NaOH added divided by the total volume) to calculate the pH using the Henderson-Hasselbalch equation:

pH = pKa + log([A-]/[HA])

pH = -log(1.8 x 10⁻⁴) + log(0.003745/2.357)

pH = 3.75

For the reactionA(g) ? 2B(g), a reaction vessel initially contains only A at a pressure of PA=1.19 atm . At equilibrium, PA =0.20 atm . Calculate the value of Kp. (Assume no changes in volume or temperature.)

Answers

The value of Kp for the reaction with equilibrium pressure of A is given as PA = 0.20 atm and the initial pressure of A is 0.0190.

What is Kp?

To find the value of Kp for the reaction, we will use the expression for the equilibrium constant in terms of the partial pressures of the reactants and the products.

Kp = (PB)²/PA

where, PB is the equilibrium pressure of B.

Initially, there is no B in the reaction vessel, so the change in pressure of B is equal to its equilibrium pressure. Using the law of conservation of mass, we can write:

PV = nRT

where, P is the pressure, V is the volume, n is the number of moles, R is the ideal gas constant, and T is the temperature.

Since there is no change in volume or temperature, we can write:

PV = constant or P₁V₁ = P₂V₂

where, P₁ and P₂ are the initial and equilibrium pressures of A, respectively. Since A is the only gas initially present in the reaction vessel, we can write:

P₁ = PA = 1.19 atm, P₂ = 0.20 atm V₁ = V₂

Therefore, P₁V₁ = P₂V₂ = PAV₁ = PBV₂

Since, the number of moles of A and B are related by the balanced chemical equation, we can write:

2(PB) = nB

Substituting, PB in terms of PA and V1, we get:

Kp = (PB)²/PA = (nB/2V₂)²/PA

Kp= (nB/2PAV₁)²/PA= (nB)²/(4P²AV₁)

where, nB is the number of moles of B.

To find the number of moles of B, we use the balanced chemical equation. 2 moles of B are produced for every mole of A that reacts. Since, the initial pressure of A was 1.19 atm and the equilibrium pressure of A was 0.20 atm, 0.99 atm of A has reacted.

Therefore, the number of moles of A that has reacted is:

nB = (0.99/1.19) = 0.8327 mol

The total number of moles of the system is the sum of the moles of A and B initially present in the reaction vessel.

nTotal = nA + nB

Initially, only A is present, so nTotal = nA = 1 mol. The number of moles of B is therefore:

nB = nTotal - nA = 1 - 0.8327 = 0.1673 mol

Substituting the values of PA, nB, and V1, we get:

Kp = (nB)²/(4P²AV1) = (0.1673)²/(4 × 1.19² × 1) = 0.0190

Therefore, the value of Kp for the reaction is 0.0190.

Answers

The pKa will be higher in the unknown acid solution. The pH of the unknown acids would not be affected by several drops of NaOH solution.

What is pKa and pH of solution?

The pKa of the unknown acid would be higher if the pH meter was incorrectly calibrated to read lower than the actual pH. This is because if the pH meter reads lower than the actual pH, the measured pH would be lower than the actual pH.

As pKa is the negative logarithm of the acid dissociation constant, Ka, which is directly proportional to the hydrogen ion concentration, [H⁺], a decrease in the measured pH would lead to a decrease in the measured [H⁺]. Since:

pKa = -log Ka = -log [H⁺] + log [HA], a decrease in [H⁺] would lead to an increase in pKa.

The pKa of the unknown acid would not be affected if several drops of NaOH missed the reaction beaker and fell onto the bench top. This is because the number of moles of NaOH that react with the unknown acid is not affected by the drops that miss the beaker.

The number of moles of NaOH that react with the unknown acid is determined by the volume and the concentration of NaOH added to the beaker and the volume and the concentration of the unknown acid in the beaker. Therefore, the pKa would remain the same.

The pKa of the unknown acid would not be affected if acid was dissolved in 75 mL of distilled water rather than 50 mL of distilled water. This is because the pKa of an acid is an intrinsic property that is independent of the amount of the acid. The pKa is determined by the acid itself, not by the amount of acid. Therefore, the pKa would remain the same.

What is partial pressure?

Partial pressure is the pressure that gas, in a mixture of gases, would exert if it alone occupied the whole volume occupied by mixture.

Part A) As λ = h / (mv) and PV = nRT

v = √(3RT/M) = √((3 x 0.08206 x 310) / 5.31 x 10⁻²⁶) = 464.5 m/s

λ = 6.626 x 10⁻³⁴ J s / (5.31 x 10⁻²⁶ kg x 464.5 m/s) = 1.75 x 10⁻¹¹ m

Therefore, thermal wavelength (or de Broglie wavelength) of diatomic oxygen at T=310K is 1.75 x 10⁻¹¹ m.

Part B)  As q_rot = (T / θ_rot) / [1 - exp(-T/θ_rot)]

θ_rot is the rotational temperature, h is Planck's constant, I is moment of inertia of the molecule, and kB is the Boltzmann constant. For O2, I = 1.94 x 10⁻⁴⁶ kg m² and θ_rot = 2.07 K.

q_rot = (310 K / 2.07 K) / [1 - exp(-310 K / 2.07 K)] = 74.9

Therefore, the rotational partition function of oxygen at T=310K is 74.9.

Part C) q_vib = 1 / (1 - exp(-θ_vib/T))

θ_vib is the vibrational temperature of the molecule.

q_vib = 1 / (1 - exp(-2260 K / 310 K)) = 2.61 x 10⁻²

Therefore, the bond vibrational partition function of oxygen gas at T=310K is 2.61 x 10⁻².

Part D) μ = m_O2 x m_heme / (m_O2 + m_heme)

μ = 32 amu x 600 amu / (32 amu + 600 amu) = 31.2 amu

ν = 1 / (2πc) x √(k / μ)

ν = 1 / (2π x 2.998 x 10⁸ m/s) x √(500 N/m / 31.2 amu) = 1.45 x 10¹³ Hz

θ_vib(bound) = hν / kB

θ_vib(bound) = (6.626 x 10⁻³⁴ J s x 1.45 x 10^13 Hz) / (1.381 x 10⁻²³ J/K) = 1600 K

Therefore, vibrational temperature of heme-bound oxygen is estimated to be 1600 K, which is lower than vibrational temperature of free oxygen gas (θ_vib(gas) ≈ 2260 K).

Part E) q_vib = 1 / (1 - exp(-θ_vib(bound)/T))

q_vib = 1 / (1 - exp(-1600 K / 310 K)) = 7.63 x 10⁻²

Therefore, vibrational partition function for oxygen bound to a heme group at T=310K is 7.63 x 10⁻².

Part F) K = (P_O2 x q_vib x exp(-w/(RT))) / Λ

K = (1.00 atm x 7.63 x 10⁻² x exp(-(-63 kJ/mol)/(8.314 J/(mol K) x 310 K))) / (1.75 x 10⁻¹¹ m) = 3.34 x 10⁵

Therefore, binding constant for the weak bond formed between oxygen and the heme group is 3.34 x 10⁵ .

Part G: K = (P_O2 x q_vib x exp(-ΔG°/(RT))) / Λ

ΔG° = -RT ln K

ΔG° = - (8.314 J/(mol K) x 310 K) x ln (3.34 x 10⁵ / (0.05 atm x 7.63 x 10⁻² x 1.75 x 10⁻¹¹m)) = -50.7 kJ/mol

Therefore, standard Gibbs energy change for binding of oxygen to the heme group at P=0.05 atm and T=310K is -50.7 kJ/mol.

Part H) ΔG° = ΔH° - TΔS°

ΔH° = ΔG° + TΔS°

ΔH° = -50.7 kJ/mol + (310 K x 70 J/(mol K)) = -28.6 kJ/mol

Therefore, standard enthalpy change for binding of oxygen to heme group at P=0.05 atm and T=310K is -28.6 kJ/mol.

Part I) As fB = [O2]/([O2] + K)

= (0.003 mol/L) / (0.003 mol/L + 3.34 x 10⁵ L/mol) = 8.95 x 10⁻⁹

Therefore, fraction of binding sites on the protein that are bound to oxygen is 8.95 x 10⁻⁹.

Answers

Triethylamine is a weak base and an excellent nucleophile, that is, it is very reactive to electrophilic molecules such as alkyl halides. Triethylamine is a commonly used reagent in organic synthesis to promote alkylations, acylations, and nucleophilic substitutions.Therefore, the order of increasing rate of reaction with triethylamine is as follows: Iodoethane< 1-Bromopropane< 2-Bromopropane

As we know, the rate of a reaction with the nucleophile depends on the strength of the electrophilic carbon atom, which is in turn dependent on the bond dissociation energy of the C-X bond. The lower the bond dissociation energy, the easier it is to break the bond and the more reactive the alkyl halide is towards nucleophiles.

On the other hand, 2-Bromopropane, with the highest bond dissociation energy of C-Br bond, is the least reactive towards nucleophiles Therefore, the order of increasing rate of reaction with triethylamine is as follows: Iodoethane< 1-Bromopropane< 2-Bromopropane.

why should the electrodes be kept in fixed relative positions during the electrolysis? is it really necessary for them to be parallel?

Answers

It is important to keep the electrodes in a fixed relative position during electrolysis as it affects the current that passes through the solution.

For example, if the electrodes are placed too close together, the current will be too strong and can cause damage to the system. Additionally, having the electrodes in a parallel position ensures that the current flows evenly through the entire solution. This is because having the electrodes parallel helps to ensure that the current flows in the same direction and not at different angles. This helps to keep the current steady and prevents hot spots or localized over-voltage. In conclusion, it is necessary to keep the electrodes in a fixed relative position, parallel to each other, during electrolysis to ensure the current is distributed evenly and not too strong.

Calculate the mass of sodium chloride required to prepare a 100cm^3 of 1.00 mol dm^-3 sodium chloride solution.( The molar mass of sodium Chloride is 58.5gmol^-1)​

Answers

Answer:

To prepare a 1.00 mol dm^-3 sodium chloride solution, we need to dissolve one mole of sodium chloride in one liter of solution (1000 cm^3).

However, we only need to prepare 100 cm^3 of the solution, which is 1/10 of a liter. So we need to dissolve:

1/10 * 1.00 mol = 0.100 mol

of sodium chloride in 100 cm^3 of solution.

The molar mass of sodium chloride is 58.5 g/mol. So to calculate the mass of sodium chloride required, we can use:

mass = number of moles x molar mass

mass = 0.100 mol x 58.5 g/mol

mass = 5.85 g

Therefore, we need 5.85 g of sodium chloride to prepare 100 cm^3 of 1.00 mol dm^-3 sodium chloride solution.

To titrate the given sodium oxalate solution, the volume of KMnO₄ needed must be determined. The molar mass of Na₂C₂O₄ is 134.00 g/mol.

Mass of Na₂C₂O₄ = 0.355 g

Moles of Na₂C₂O₄ = (0.355 g)/(134.00 g/mol) = 0.00265 mol

From the balanced equation, it can be seen that 2 moles of KMnO₄ are required to react with 5 moles of Na₂C₂O₄. As a result, the number of moles of KMnO₄ needed can be calculated.

Moles of KMnO₄ = (2/5) × 0.00265 mol = 0.00106 mol

The volume of 0.0100 M KMnO₄ needed can now be determined using the molarity equation.

Molarity (M) = moles (n) / volume (V)

n = M × V

V = n / M = 0.00106 mol / 0.0100 M = 0.106 L = 0.0234 L (to three significant figures)

Therefore, to titrate a solution containing 0.355 g of sodium oxalate, 0.0234 L of 0.0100 M KMnO₄ is needed.

Why do we use anhydrous diethyl ether? Choose the right answer.

A. Since Grignard reagents react with O2 to form hydroperoxides, vapors from highly volatile diethyl ether solvent prevents O2 from reaching the reaction mixture.

B. Ether molecules coordinate with grignard Reagent

C. Ether helps stabilize the Grignard reagent

Answers

We use anhydrous diethyl ether since Grignard reagents react with O2 to form hydroperoxides, vapors from highly volatile diethyl ether solvent prevents O2 from reaching the reaction mixture. Option A is the correct answer.

Anhydrous diethyl ether is commonly used as a solvent in Grignard reactions. The main reason for using anhydrous diethyl ether is to prevent the Grignard reagent from reacting with moisture or oxygen in the air, which would lead to unwanted side reactions or a reduction in the yield of the desired product.

Diethyl ether is highly volatile, and its vapors help to exclude oxygen from the reaction mixture, preventing the formation of hydroperoxides. Additionally, diethyl ether helps to dissolve the reactants and stabilize the Grignard reagent, making it more reactive towards the substrate. Hence option A is correct.

Plutonium-238 is a radioactive element used as a power source in spacecraft like Voyager and New Horizons. It has a half life of 87.7 years. Suppose we have 2 kg of plutonium-238 right now. How much plutonium will be left in 87.7 years? A) None B) 0.25 kg C) 0.5 kg D) 1.0 kg E) 2 kg

Answers

The answer is C) 0.5 kg. This is because Plutonium-238 has a half-life of 87.7 years, which means that after 87.7 years, half of the original amount of Plutonium-238 will remain. In this case, that would be 2 kg * 0.5 = 0.5 kg.

Plutonium-238 is a radioactive element used as a power source in spacecraft like Voyager and New Horizons. It has a half-life of 87.7 years. Suppose we have 2 kg of plutonium-238 right now. Radioactive decay is a random event. So, it is impossible to predict when a specific atom will decay. But we can find how much radioactive material is remaining after a specific period of time.

The half-life of a radioactive material is the time required for half of the radioactive material to decay. The formula to calculate the remaining material is:

N(t) = N0 × (1/2)^(t/t1/2)

Where N(t) is the remaining material at time t, N0 is the initial material, t1/2 is the half-life, and t is the elapsed time.

The initial material is 2 kg, half-life is 87.7 years, and the elapsed time is also 87.7 years.

N(87.7) = 2 kg × (1/2)^(87.7/87.7)= 1 kg × 0.5= 0.5 kg

Therefore, the amount of plutonium remaining after 87.7 years will be 0.5 kg. So, the answer is option C.

many tests to distinguish aldehydes and ketones involve the addition of an oxidant. only choose... can be easily oxidized because there is choose... next to the carbonyl and oxidation does not require choose...

Answers

The tests to distinguish aldehydes and ketones involve the addition of an oxidant. This is because aldehydes can be easily oxidized because there is a hydrogen next to the carbonyl, and oxidation does not require a catalyst.

In general, aldehydes and ketones can be differentiated by the use of a wide range of chemical reagents. Tests for detecting these functional groups are usually based on their distinctive properties, such as the capacity to react with oxidizing agents or nucleophiles, which give different functional group products when they interact with aldehydes or ketones. Since these functional groups have differing properties, it is critical to employ distinct methods for their identification.

However, the use of oxidizing reagents to differentiate between aldehydes and ketones is one of the most frequent approaches. This is due to the presence of a hydrogen atom attached to the carbonyl group in aldehydes, which is readily oxidized by reagents such as Tollens' reagent (Ag2O/NH3) or Benedict's reagent (CuSO4 + NaOH). Hence, many tests to distinguish aldehydes and ketones involve the addition of an oxidant, this is because aldehydes can be easily oxidized because there is a hydrogen next to the carbonyl, and oxidation does not require a catalyst. Therefore, the third option is the only correct one.

How many molecules of oxygen are produced by the decomposition of 6. 54 g of potassium chlorate (KCLO3)?

Answers

The breakdown of 6.54 g of potassium chlorate results in the production of 4.81 x [tex]10^{22}[/tex]oxygen molecules.

The balanced chemical equation for the decomposition of potassium chlorate is:

2 KClO3(s) → 2 KCl(s) + 3 O2(g)

This equation tells us that for every 2 moles of potassium chlorate that decompose, 3 moles of oxygen gas are produced.

To determine the number of molecules of oxygen produced by the decomposition of 6.54 g of potassium chlorate, we first need to convert the mass of potassium chlorate to moles using its molar mass. The molar mass of KCLO₃ is:

K: 39.10 g/mol

Cl: 35.45 g/mol

O: 3(16.00 g/mol) = 48.00 g/mol

Total molar mass of KCLO₃: 39.10 + 3(35.45) + 48.00 = 122.55 g/mol

Number of moles of KCLO₃ = 6.54 g / 122.55 g/mol = 0.0533 mol

Now we can use the mole ratio from the balanced equation to calculate the number of moles of oxygen produced:

3 moles O₂ / 2 moles KCLO₃ = x moles O₂ / 0.0533 moles KCLO₃

x = 3/2 x 0.0533 = 0.0799 moles O₂

Finally, we can convert the number of moles of oxygen to the number of molecules using Avogadro's number:

Number of molecules of O2 = 0.0799 mol x 6.022 x [tex]10^{23}[/tex] molecules/mol = 4.81 x [tex]10^{22}[/tex] molecules

Therefore, 4.81 x [tex]10^{22}[/tex] molecules of oxygen are produced by the decomposition of 6.54 g of potassium chlorate.

Explain the significance of the line spectrum observed for the hydrogen atom by Neil bohr. What were the inadequacies of the bohr model? calculate the energy required to excite a hydrogen electron from level n=1 to n=3

Answers

The line spectrum observed for the hydrogen atom by Niels Bohr is significant because it provided evidence for the quantization of energy levels in atoms.

Bohr's model proposed that electrons in atoms occupy specific energy levels or orbits around the nucleus, and that they can only absorb or emit energy in discrete amounts as they transition between these energy levels. When an electron in hydrogen is excited to a higher energy level by absorbing energy, it eventually returns to its original energy level by emitting energy in the form of light, which is observed as the line spectrum.

However, the Bohr model had some inadequacies. It couldn't explain the spectral lines of atoms other than hydrogen, and it couldn't account for the fine structure of spectral lines due to electron spin. Also, the model violated the Heisenberg uncertainty principle, which states that it is impossible to simultaneously determine the exact position and momentum of an electron.

To calculate the energy required to excite a hydrogen electron from level n=1 to n=3, we can use the formula:

ΔE = E3 - E1 = (-13.6 eV/n²) [(1/3²) - (1/1²)]

where E1 and E3 are the energy levels corresponding to n=1 and n=3, respectively. Plugging in the values gives:

ΔE = (-13.6 eV/n²) [(1/3²) - (1/1²)] = (-13.6 eV) [(1/9) - 1] = 10.2 eV

Therefore, the energy required to excite a hydrogen electron from level n=1 to n=3 is 10.2 eV.

Select the correct molecule that is the main product of the Calvin cycle.
1. G3P
2. NADPH
3. Glucose

Answers

The  molecule that is the main product of the Calvin cycle is glucose. The Calvin cycle is also known as the light-independent reactions.

It is a series of biochemical reactions that occur in the stroma of the chloroplast in photosynthetic organisms to produce glucose. The Calvin cycle is made up of three stages: Carbon fixation, Reduction and regeneration of ribulose bisphosphate. Here's a breakdown of each stage:

Carbon fixation: Carbon dioxide enters the Calvin cycle and is converted to organic molecules. During carbon fixation, Rubisco, which is a crucial enzyme in photosynthesis, catalyzes the reaction between carbon dioxide and ribulose bisphosphate, leading to the formation of a six-carbon molecule that splits into two three-carbon molecules. This three-carbon molecule is the starting material for the reduction process.

Reduction: The ATP and NADPH produced during the light-dependent reactions are used to convert the three-carbon molecule produced during carbon fixation into glyceraldehyde-3-phosphate. This process involves a series of biochemical reactions that require the use of energy from ATP and electrons from NADPH.

Regeneration of ribulose bisphosphate: Glyceraldehyde-3-phosphate, which is the main product of the Calvin cycle, is used to regenerate the starting material for carbon fixation, ribulose bisphosphate. During this stage, ATP is used to convert the remaining glyceraldehyde-3-phosphate molecules into ribulose bisphosphate. The Calvin cycle is an essential process in photosynthesis, as it produces glucose, which is the main source of energy for plants and other photosynthetic organisms.

The thioketal product of a certain reaction is given below. Draw the structure of: the organic reactant the protecting group reactant H r

Answers

Answer: The organic reactant is 1,3-propanedithiol. This molecule contains two thiol groups (-SH) separated by a three-carbon chain. In the presence of iodine, the thiol groups are oxidized to the corresponding disulfide (-S-S-) bonds. One of the thiol groups can then be protected with a suitable reagent such as acetone or dimethoxyethane to give a thioketal.

Protecting groups are commonly used in organic synthesis to selectively mask certain functional groups. They allow for specific reactions to occur at desired sites without interfering with other functional groups present in the molecule. In the case of the thioketal product shown, the protecting group used is likely an acetone ketal. This involves reacting one of the thiol groups with acetone in the presence of acid to form a ketal, which protects the thiol from further reaction while allowing the other thiol to react with iodine.

conjugate base, hydrogen atom, negative charge

Answers

An acid donates a proton to form its conjugate base, which therefore has one less hydrogen atom and one more negative charge than its acid. The strength of an acid depends on its ability to donate a proton to form its conjugate base. The weaker the acid, the stronger the conjugate base, and the stronger the acid, the weaker the conjugate

base.The conjugate base of a strong acid is weak because it has a very low ability to accept another proton since it is already carrying a negative charge. A weak acid has a strong conjugate base since it has a high ability to accept

another proton. Thus, an acid and its conjugate base are related to each other in terms of their ability to donate or accept a proton. For example, hydrochloric acid (HCl) dissociates in water to form H+ and Cl-. Its conjugate base is

chloride (Cl-) which is strong since it cannot accept another proton to form HCl again.
