Chemistry - Ionic Equilibrium Question with Solution | TestHub

${\text{A}}_{\text{3}}\text{B(aq)}\rightleftharpoons \underset{\text{3s}}{{\text{3A}}^{\text{+}}}\text{+}\underset{\text{s}}{{\text{B}}^{\text{3}-}}$
${\mathrm{K}}_{\mathrm{s}\mathrm{p}}=27{\mathrm{s}}^3\times \mathrm{s}$
$=27{\mathrm{s}}^4$
$\mathrm{s}={\left(\frac{{\mathrm{K}}_{\mathrm{s}\mathrm{p}}}{27}\right)}^{1/4}$
