If silver phosphate has a Ksp of 2.28e-16 at a certain temperature, what is the molar solubility of silver phosphate at the same temperature?

Answer 1

..........Ag3PO4 ==> 3Ag^+ + PO4^3-
I.........solid.......0.......0
C.........solid.......3x......x
E.........solid.......3x.......x

Substitute the E line into Ksp expression and solve for x = molar solubility
