Chemistry - Ionic Equilibrium Question with Solution | TestHub

Consider the equilibrium, for which $\Delta \mathrm{H}<0$,

HgO(s) + 4I⁻(aq) + H₂O(l) $\rightleftharpoons$ HgI₄²⁻ + 2OH⁻

Which change(s) will increase the equilibrium concentration of HgI₄²⁻?

I. Increasing the mass of $\mathrm{HgO}(\mathrm{s})$ present.

II. Increasing [ ${\mathrm{I}}^{-}$]

III.Adding 1 M HCl .
