I got this question in homework.

This key question is from Types of Solutions topic in division Solutions of Chemistry – Class 12

Answer 1

Correct answer is (d) The solute precipitates out of the solution

For explanation: When a solute crystal is added to a supersaturated solution, solute particles leave the solution and forms a crystalline precipitate. The addition of the solute crystal is also called seeding.
