We're being asked to calculate the Ksp for each compound

a. BaCrO4; molar solubility = 1.08 x 10-5

The dissociation of BaCrO4 in water is as follows:
BaCrO4(s) → Ba2+(aq) + CrO42(aq)

We can construct an ICE table for the dissociation of BaCrO4

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

The Ksp expression for BaCrO4 is:
