How can a saturated solution of a solid be made unsaturated?
a).by increasing the temperature of the solvent
b).by decreasing the temperature of the solvent
c).by stirring the solution
e).by adding more solute
d).a saturated solution cannot be made unsaturated

The correct answer is Option A.

Explanation:

A saturated solution is defined as the solution in which no more solute can be dissolved in a given amount of solvent.

An unsaturated solution is defined as the solution in which more solute can be dissolved in a given amount of solvent.

Solubility of solute in a solvent is directly related to the temperature of the solvent.

Increasing the temperature will increase the solubility of solute in solvent and hence, making the solution unsaturated.

Therefore, the correct answer is Option A.

the answer to your question is c
