Question

Silver ion will react with cyanide ions to form the complex ion Ag(CN)2-

a) Silver chloride is almost insoluble in pure water, but it is much more soluble in a solution containing sodium cyanid due to the foramation of the Ag(CN)2- complex ion

ii) Write a balanced chemical reaction for the dissolving of AgCl (s) in the presence of excess CN- (ag), and determine the unmerical value of the equilibrium constant for this reaction. Please include state symbols such as (s) and (aq).
