Consider the equilibrium:

$H g O (s) + 4 I^{-} (a q) + H_{2} O (l) ⇌ H g I_{4}^{2 -} (a q) + 2 O H^{-} (a q)$

Which changes will decrease the equilibrium concentration of $H g I_{4}^{2 -}$ ?

Answer:

C, D

Solution:

Le Chaterler's Principle.

For decreasing $[HgI_{4}]^{2 -}, Q > K$ .

$Q = \frac{[ HgI _{4}^{2 -} ] [ OH ^{-} ] ^{2}}{[ I ^{-} ] ^{4}}$
