A solution contains 0.020 M Mg2+ and 0.10 M Ca2+. Can 99.90% of Mg2+ be precipitated by addition of NaOH without precipitation of Ca2+? Note: use Ksp = 7.1 x 10-12 for Mg(OH)2 Ksp= 5.5 x 10^-6 CaOH2
A solution contains 0.0500 M Co2+and 0.0500 M Ni2+. Is it possible to lower the concentration of Co2+by 99.9% without precipitating Ni2+by adding Na2CO3to the solution? Ksp,CoCO3= 1.0 x 10-10and Ksp,NiCO3= 1.3 x 10-7 Please show work so I can understand why this is the answer! Answer: Yes, it is possible. (QNiCO3 < Ksp,NiCO3, no precipitation)

Purifying Mg2+ from sea water. Aqueous sodium hydroxide is added to an aqueous solution that contains 0.0099 M magnesium chloride and 0.021 M calcium chloride. What will be the concentration of the metal ion that precipitates first (as M(OH)2) at the time the second metal ion begins to precipitate? Ksp (Mg(OH)2) = 6.3 x 10-10 and Ksp (Ca(OH)2) = 6.5 x 10-6 Hint: Use Ksp values to determine the solubility of each product to determine the order of precipitation.
