For this problem, we’re being asked to calculate the molar solubility of AgI.
Since the AgI is an ionic compound, it forms ions when dissociating in water. The dissociation of AgI in water is as follows:
The hydroxide ion, OH–, has a charge of –1. Nickel then has a charge of +2:
AgI(s) ⇌ Ag+(aq) + I–(aq)
We can construct an ICE table for the dissociation of AgI.
Remember that solids are ignored in the ICE table and Ksp expression.
Determine the molar solubility of AgI in pure water.
Ksp (AgI)= 8.51 x 10-17
