A sоdium sulfаte (Nа2SO4) sоlutiоn is аdded to a 1.5 × 10-3 M solution of calcium sulfate (CaSO4). The precipitation of calcium sulfate starts when the concentration of Na+ in solution reaches 0.063 M. What is the Ksp of calcium sulfate? You can ignore volume change of the calcium sulfate solution upon adding sodium sulfate. Potentially helpful equations: Na2SO4(aq) → 2 Na+(aq) + SO42¯(aq)CaSO4(s) ⇋ Ca2+(aq) + SO42¯(aq) Ksp = ?
