Question

Explain the relation between ionic product and solubility product to predict whether a precipitate will form when two solutions are mixed?

Answer 1

If ionic product and solubility product are indicated by IP and K_sp respectively then,

(I) When IP = K_sp, the solution is saturated.

(II) When IP > K_sp, the solution is supersaturated and hence precipitation will occur, when two solutions are mixed.

(Ill) When IP < K_sp, the solution is unsaturated and precipitation will not occur, when two solutions are mixed.
