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