We’re being asked to determine Ksp of Cu3(PO4)2
Recall that Ksp is an equilibrium constant related to slightly soluble ionic compounds.
The dissociation of magnesium carbonate in solution is as follows:
Cu3(PO4)2(s) ⇌ Cu2+(aq) + PO43–(aq)
We can construct an ICE table for this dissociation.
Remember that solids are ignored in the ICE table and Ksp expression.
Given that the solubility of Cu3(PO4)2 is 1.7 x 10-8 mol/L what is its Ksp value?
