Answer:
Explanation:
1- Cathode 2- copper electrolyte solution usually (CuSO4) 3- Cu half cell 4- bulb (when lighted, shows the current is flowing) 5- Zn half cell 6- Zn electrolyte solution 7- connecting wires 8- anode (Zn) 9-salt bridge
2- the copper-(Cu) electrode is the cathode and the zinc-(Zn) electrode will be the anode. This is because the cathode is negatively charged (while Cu is positively charged, so it attracts) and the anode is positively charged (while Zn will be negative)
3- the electrons flow from the anode, where oxidization takes place, to the cathode, where reduction reactions take place.
That's the best i can do. Hope it helps.
Answer:
Explanation:
• Label all parts (1–9), including the solutions in each beaker and the connecting tube.
1. Copper strip
2. Cu2+(aq) (copper electrolyte solution or copper nitrate)
3. Cathode compartment
4. Light bulb
5. Anode compartment
6. Zn2+ (aq) (zinc electrolyte solution or zinc nitrate)
7. The connecting wires or the external circuit
8. Zinc strip
9. Salt bridge
• Label which cell is the cathode and which cell is the anode. Include the charge on each strip.
The copper strip is the cathode and the zinc strip is the anode. The anode is positively charged and the cathode is negatively charged. This is because the cathode attracts a positive charge and the anode attracts a negative charge.
• Show, or describe in detail, the flow of electrons.
The atoms from the zinc strip are oxidized into zinc ions, (the anode is where oxidation occurs). The electrons in the anode then travel through the wire to the copper strip. The electrons then merge with the copper ions in the solution creating copper metal (the cathode is where reduction occurs).
• Describe what type of electrochemical cell is pictured. Explain how the cell works. Include the oxidation and reduction half-reactions in your explanation.
This is a voltaic or galvanic cell. It works by using spontaneous oxidation-reduction reaction to generate electricity.
Zn(s) --- Zn2 + (aq) + 2e-
Cu2 + (aq) + 2e- --- Cu(s)
