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.
The concentration of Mg2+ at equilibrium (25oC) is 0.000144 M. What is the value of Ksp at this temperature? In the solubility rules, Mg(OH)2 was listed as an "insoluble" salt. It is actually slightly soluble in an equilibrium reaction: Mg (OH)2 (s) Mg2+ (aq) 20H (aq) The concentration of Mg2+ at equilibrium (25°C) is 0.000144 M. What is the value of Ksp at this temperature? Submit Answer Tries o/99
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
