Dichlor-palladous Acid, H2PdCl2(OH)2






On adding a silver salt to a solution of palladous chloride a precipitate is obtained, not of silver chloride, but of a complex compound of composition PdCl2.2AgOH or [PdCl2(OH)2]Ag2. It seems possible, therefore, that palladous chloride can, in aqueous solution, act like an acid, yielding the ions:



In addition to the silver salt, the lead and thallium derivatives, [PdCl2(OH)2]Pb.Pb(OH)2 and [PdCl2(OH)2]Tl2 respectively, have also been obtained.

All three salts are hydrolysed by hot water, the silver salt being the least sensitive.
