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
D.
by adding more solute
E.
a saturated solution cannot be made unsaturated

1 answer

A saturated solution contains the maximum amount of solute that can dissolve in a solvent at a given temperature. To make a saturated solution unsaturated, you can reduce the concentration of solute in the solution.

The most effective way to achieve this is:

A. by increasing the temperature of the solvent

Increasing the temperature typically increases the solubility of solids, allowing more solute to dissolve and thus making the solution unsaturated.

Therefore, the correct answer is A. by increasing the temperature of the solvent.
