Write the equilibrium equation (Keq), the solubility expression (Ksp) and calculate the solubility of PbSO4 in mole/ L. The Ksp value of PbSO4 is 1.3*10^-8

Answer 1

.............PbSO4 ==> Pb^2+ + [SO4]^2-
I...............solid............0............0
C..............solid............x.............x
E...............solid............x.............x
Ksp = (Pb^2+)(SO4^2-)^2- = 1.3E-8
Plug in the E line into the Ksp expression and solve for x = solubility in mols/L for PbSO4.
