Interpretation of the solubility product (Salze-71)
Given the solubility product of Lp(CaSO4) = 2·10-5 mol2/l2. Is a solution with c(Ca2+)= 10-2 mol/l and c(SO2-4) = 10-4 mol/l contains, unsaturated, saturated or over-saturated? Notes : The following applies (to known masses): — Saturated solution ion product = Lp — Non-saturated solution ion product < Lp — Saturated solution ion product > Lp
