In order to have precipitation the solution should be...​

Answer 1

Answer:

A solution must be saturated to be in equilibrium with the solid. ... A supersaturated solution is not at equilibrium, and no solid can ordinarily be present in such a solution. If some of the solid is added, the excess ions precipitate out and until solubility equilibrium is achieved.
