Essay

A solution was prepared such that the initial concentrations of Cu²⁺(aq)and CN^-(aq)were 0.0120 M and 0.0400 M, respectively. These ions react according to the following chemical equation
Cu²⁺(aq)+ 4CN^-(aq) Cd(CN)₄^2-(aq)K_c = 1.0 * 10²⁵
What will be the concentration of CN^-(aq)at equilibrium?
