Question 1

Solid sodium iodide is slowly added to a solution that is 0.0050 M Pb2+ and 0.0050 M Ag+. [Ksp (PbI2) = 1.4 × 10–8; Ksp (AgI) = 8.3 × 10–17] What percent of Ag+ remains in solution at this point?

Question 2

The concentration of Mg2+ in seawater is 5.0 × 10–2 M.  What hydroxide concentration is needed to remove 90% of the Mg2+ by precipitation?   (For Mg(OH)2, Ksp = 1.2 × 10–11.)
