Selective Precipitation y A solution contains 1.5 x 10 -4 M of both Mg 2+ and Ba 2+ ions. A source of OH - is added slowly to this solution, will Mg(OH) 2 (K sp = 8.9 x 10 -12 ) or Ba(OH) 2 (K sp = 5.0 x 10 -3 ) precipitate first? Specify the concentration of OH - necessary to begin precipitation of each salt.
