Question

When a crystal of a solute is introduced into a supersaturated solution of the solute:

• A. the solute dissolves
• B. the solution becomes unsaturated
• C. the solution remains supersaturated
• D. the excess of solute crystallises out

Answer 1

Answer: (C)

the solution remains supersaturated

A supersaturated solution is a solution that contains less than the maximum amount of solution per given amount of solvent at a particular temperature. When more solutions is added to a supersaturated solution the solution will crystallize rapidly to form crystals and hence remains supersaturated only.
