The equilibrium reactions happening in this system are:
And the complexation equilibrium:
(Of course, the autoionization of water is an ubiquitous equilibrium in all aqueous systems):
A single reaction that could sum all of the equilibriums would be:

1) A solution that is 500 molar HCN, K.-6.2 x 10-10 is in equilibrium with solid silver (1) cyanide, Ksp - 2.2 x 10. However, it is known that silver (I), Ag'. can complex under certain conditions with CN to produce the silver (1) dicyano complex, Ag(CN)2] . log Kr - 20.48. What are all of the equilibrium reactions that are occurring in this solution? Is there a single overall reaction that can describe the equilibria in this solution?
H. Complex Ions 1. Silver chloride has very low solubility in water (Ks of 1.6 x 10-19), however, it is highly soluble in an ammonia solution due to the formation of the complex ion [Ag(NH3)21 (Kr" 1.7 X 10) Given this information, calculate the molar solubility of AgCl in 2.25 M ammonia. 2.
