Admium(II) chloride is added to a solution of potassium hydroxide with a pH of 9.62. (Ksp Cd(OH)2 = 2.5 X 10-14)
(a) At what concentration of Cd 2+ does a precipitate first start to form?
(b) Enough cadmium(II) chloride is added to make Cd2+ 0.0013 M. What is the pH of the resulting solution?
(c) What percentage of the original hydroxide ion is left in solution?
