Explanations about the differences of
the two solutions
Saturated solution
Unsaturated solution​

Answers

Answer:

See explanation

Explanation:

A saturated solution is a solution that contains just as much solute as it can normally hold at a given temperature in the presence of undissolved solute. An unsaturated solution contains less solute than it can normally hold at a given temperature. A saturated solution can not dissolve more solute whereas an unsaturated solution can comfortably dissolve more solute until it attains saturation at a specified temperature.
