Problem: Use values of Ksp for AgI and Kf for AgCN2-Determine the molar solubility of AgI in a 0.160 M NaCN solution.

FREE Expert Solution

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:

Ksp = productsreactants = [Ag+][I- ]Solids and liquids are ignored in the Ksp equation.
