Solution:
- PLAN In presence of common ion (in this case
Let solubility of $\mathrm{Ag}{2} \mathrm{CrO}{4}
$$ \begin{aligned} & \mathrm{AgNO}{3}=x \ & \mathrm{Ag}{2} \mathrm{CrO}{4} \rightleftharpoons 2 \mathrm{Ag}^{+}+\underset{x}{\mathrm{CrO}{4}^{2-}} \ & \mathrm{AgNO}{3} \rightleftharpoons \underset{0.1}{\mathrm{Ag}^{+}}+\underset{0.1}{\mathrm{NO}{3}^{-}} \end{aligned} $$
Total
Thus, $\quad\left[\mathrm{Ag}^{+}\right]^{2}\left[\mathrm{CrO}{4}^{2-}\right]=K{\text {sp }}$
