Problem: What is the solubility of the insoluble salt MX2?

FREE Expert Solution

For this problem, we’re being asked to determine the solubility of the insoluble salt MX2


Since the MX2 is an ionic compound, it forms ions when dissociating in water. The dissociation of MX2 in water is as follows:


Assuming M has a charge of +2. The X ion, X, has a charge of –1.

MX2(s)  M2+(aq) + 2 X(aq)



We can construct an ICE table for the dissociation of MX2

Remember that solids are ignored in the ICE table and Ksp expression.
