We are being asked to calculate the molar solubility of AgI in 0.160 M NaCN solution.
Since the compounds are ionic compounds, they form ions when dissociating in water. The dissociation of AgI in water are as follows:
AgI(s) ⇌ Ag+ (aq) + I- (aq)
The solubility product constant of AgI is 8.51 x 10-17(can be found in a textbook or on the internet)
Solubility product expression for AgI:
Solids and liquids are ignored in the Ksp equation.
Use values of Ksp for AgI and Kf for AgCN2-
Determine the molar solubility of AgI in a 0.160 M NaCN solution.
