Question

The value of Ksp for Cd(OH)₂ is 2.5 x 10^-14. (a) What
is the molar solubility of Cd1OH22? (b) The solubility
of Cd(OH)₂can be increased through formation of the
complex ion CdBr₄^{2 -} (Kf = 5 x 10³). If solid Cd(OH)₂ is
added to a NaBr solution, what is the initial concentration
of NaBr needed to increase the molar solubility of Cd(OH)₂
to 1.0 x 10^-3 mol/L?
