You add 10.0 grams of solid copper(II) phosphate, Cu3(PO4)2 , to a beaker and then add 100.0 mL of water to the beaker at T = 298 K . The solid does not appear to dissolve. You wait a long time, with occasional stirring and eventually measure the equilibrium concentration of Cu2+(aq) in the water to be 5.01×10−8 M . What is the Ksp of copper(II) phosphate?
