You need to solve the Ksp expression to determine the solubility of PbSO4.
PbSO4 ==> Pb^+2 + SO4^-2
(Pb^+2)(SO4^-2) = Ksp.
Let S = (Pb^+2); then S = (SO4^-2)
Substitute into the Ksp expression and solve for S. Compare S with the value given in the problem (1.0 x 10^-4 M) to determine if it is saturated or not.
Suppose a solution contains a concentration of 1.0x10^-4M PbSO4 (Ksp=1.8x10^-8). Which of the following terms describes this solution?
saturated , unsaturated, supersaturated, or cannot be determined
