What may happen when a seed crystal is added to a supersaturated solution?
Answer and explanation
Correct answer: Crystallization may start
A supersaturated solution holds more dissolved solute than is normally stable. A seed crystal supplies an ordered surface onto which excess solute particles can attach, so nucleation and crystal growth can begin. The solute is not destroyed; it changes from dissolved particles into a solid crystal. The seed does not make solubility infinite or turn the solvent into a gas.
