Problem: Which of the following will be more soluble in an acidic solution than in pure water? PbSO4, Cd(OH)2, CsClO4, AgCl.

FREE Expert Solution

For PbSO4:  PbSO4 dissociates to form Pb2+ and SO42.

Cation: Pb2+ is a main group metal cation with a +2 charge  Pb2+ is a neutral ion

Anion: Addition of 2 H+ to SO42- forms H2SO4, a strong acid  SO42- is a neutral ion


Therefore, PbSO4 is a neutral salt and will have no change in solubility in an acidic solution.
