Chemistry - Ionic Equilibrium Question with Solution | TestHub

${\text{Ag}}_2{\text{CrO}}_4\rightleftharpoons {\text{2Ag}}^{+}+{\text{CrO}}_4^{2-}\text{;}{\text{K}}_{\text{sp}}=\text{1.1}\times {\text{10}}^{-\text{12}}$
S                     2S            S

${\text{K}}_{\text{sp}}={\left[{\text{Ag}}^{+}\right]}^2·\left[{\text{CrO}}_4^{2-}\right]$

K_sp= [2S]²·[S] = 4S³

${\text{S}}^3=\frac{K_{\mathit{sp}}}{4}\mathit{}=\frac{1.1\times {10}^{-12}}{4}$

$⟹\text{S}=6.53\times {10}^{-5}$
