Q. Consider the reaction $HCN_{(aq)} \rightleftharpoons H^{+}_{aq} + CN^{-}_{(aq)}.$ At equilibrium, the addition of $CN^{-}_{(aq)}$ would

Equilibrium

Solution:

At equilibrium, the addition of $(CN)^{-}$ would decrease the $(H^{+})$ ion concentration to produce more and more HCN to nullified the increase of $CN^{-}_{aq}$
