Question
Will cadmium hydroxide precipitate from 0.01M solution of cadmium chloride at pH 9. Ksp of cadmium hydroxide =2. 5×10-14 mole2/dm6
Answers
pH = 9 means pOH = 5 so (OH^-) = 1E-5
Substitute and solve for Qsp.
Qsp = (Cd^2+)(OH^-)^2 and compare that with Ksp. If Ksp is smaller there is a ppt. If Ksp is larger there is no ppt.
