Homework Answers
Mg(OH)2 Ksp = 5.61 x 10^ -12 M
99.9 % Mg2+ of 0.053 = ( 99.9/100) x 0.053 = 0.052947 , [Mg2+] left free = 0.053-0.052947 = 0.000053 M
now Ksp = [Mg2+] [OH-]^2
5.61x 10^ -12 = 0.000053 [OH-]^2
[OH-] = 1.06 x 10^ -7 M
Thus minimum hydroxide needed = 1.06 x 10^ -7 M
No sodium ions will get precipitated
No Calcium ions will get precipitated

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.
