Question:

A solution contains 0.01 M {eq}\rm Ba^{2+} {/eq} and 0.01 M {eq}\rm Ag^+ {/eq}. Can {eq}\rm 99.92\% {/eq} of either ion be precipitated by chromate ({eq}\rm CrO_4^{2-} {/eq}) without precipitating the other metal ion? The {eq}\rm K_{sp} {/eq} for {eq}\rm BaCrO_4 {/eq} is {eq}\rm 2.1 \times 10^{-10} {/eq} and {eq}\rm K_{sp} {/eq} for {eq}\rm Ag_2CrO_4 {/eq} is {eq}1.2 \times 10^{-12} {/eq}.

Solubility Product Constant:

The equilibrium constant for the dissolution of a sparingly soluble salt is known as the solubility product constant. The value of the solubility product constant can give the extent of dissociation of a particular salt. The lower the value, the less soluble a salt is.
