Lead(II) hydroxide

Lead(II) hydroxide

Lead(II) hydroxide, Pb(OH)2, is a hydroxide of lead, with lead in oxidation state +2. Although it appears a fundamentally simple compound, it is doubtful if lead hydroxide is stable as a solid phase [G.Todd and E. Parry, "Character of Lead Hydroxide and Basic Lead Carbonate", Nature, 202, 386-387 (25 April 1964).] . Lead basic carbonate (PbCO3·2Pb(OH)2) or lead(II) oxide (PbO), is encountered in practice where lead hydroxide is expected. This has been a subject of considerable confusion in the past.

In solution, lead(II) hydroxide is a somewhat weak base, forming lead(II) ion, Pb2+, under weakly acidic conditions. This cation hydrolyzes and, under progressively increasing alkaline conditions, forms Pb(OH)+, Pb(OH)2(aqueous), Pb(OH)3−, and Pb(OH)42−.
