Question

Consider the equilibrium HgO(s) + 4I– (aq) + H2O(l) $\rightleftharpoons$HgI42–(aq) + 2OH– (aq), which changes will decrease the equilibrium concentration of HgI42− (aq)?

Options

A.Addition of 0.1 M-HI(aq).
B.Addition of HgO(s).
C.Addition of H2O(l).
D.Addition of KOH(aq).

Solution

Addition of water will shift the reaction in the direction of increase in mole of aq species.
