For the reaction: [Ag(CN)2]−(aq)⇌Ag+(aq)+2CN−(aq)[\text{Ag(CN)}_2]^-(\text{aq}) \rightleftharpoons \text{Ag}^+(\text{aq}) + 2\text{CN}^-(\text{aq}), KcK_c at 25°C25°\text{C} is 4×10−194 \times 10^{-19}. Calculate [Ag+][\text{Ag}^+] in a solution which was originally 0.1 M0.1\,\text{M} in KCN\text{KCN} and 0.03 M0.03\,\text{M} in AgNO3\text{AgNO}_3.
