Note: If you add concentrated hydrochloric acid to excess, the lead(II) chloride precipitate will dissolve again. You could use things like sodium chloride solution to provide the chloride ions, but it is usually easier just to add some dilute hydrochloric acid. Lead(II) chloride can be made as a white precipitate by adding a solution containing chloride ions to lead(II) nitrate solution. I am using these particular versions of the equations to keep them in line with the corresponding reaction between lead(II) oxide and sodium hydroxide solution on the oxides of Group 4 page - also a simplification! You will get complexes formed involving hydroxide ions, but the formulae of these aren't very clear-cut. Note: These equations are simplifications. If more sodium hydroxide solution is added, the precipitate redissolves to give a colourless solution which might be called sodium plumbate(II) solution - but could be called by a lot of alternative names depending on exactly how the formula is written! If a little sodium hydroxide solution is added to colourless lead(II) nitrate solution, a white precipitate of lead(II) hydroxide is produced. It describes the reactions to form lead(II) hydroxide, lead(II) chloride, lead(II) iodide and lead(II) sulphate.īecause of the insolubility of so many lead(II) compounds, the usual source of lead(II) ions in solution is lead(II) nitrate solution - and that will be assumed in all the following examples. ^ "Process of manufacturing white lead".This page looks at the formation of some insoluble lead(II) compounds from aqueous lead(II) ions using precipitation reactions.^ "Process of treating lead hydrate produced by electrolysis"."Structure of Tin(II) "Hydroxide" and Lead(II) "Hydroxide". ^ a b Von Egon Wiberg, Nils Wiberg, Arnold Frederick Holleman, "Inorganic Chemistry", Academic Press, 2001 (Google books).: CS1 maint: multiple names: authors list ( link) "An Investigation of the Lead(II)−Hydroxide System".

This cation hydrolyzes and, under progressively increasing alkaline conditions, forms Pb(OH) +, Pb(OH) 2(aqueous), Pb(OH) 3 −, and other species, including several polynuclear species, e.g., Pb 4(OH) 4 4+, Pb 3(OH) 4 2+, Pb 6O(OH) 6 4+. In solution, lead(II) hydroxide is a somewhat weak base, forming lead(II) ion, Pb 2+, under weakly acidic conditions. The structure is reminiscent of the Mo 6S 8 subunit of the Chevrel phases. This material is a cluster compound, consisting of an octahedron of Pb centers, each face of which is capped by an oxide or a hydroxide. Careful hydrolysis of lead(II) acetate solution yields a crystalline product with a formula 6PbO♲H 2O = Pb 6O 4(OH) 4. When a hydroxide is added to a solution of a lead(II) salt, a hydrated lead oxide PbO However, subsequent research has demonstrated that lead(II) hydroxide does indeed exist as one of a series of lead hydroxides. This has been a subject of considerable confusion in the past. Pb(OH) 2) or lead(II) oxide (PbO) was encountered where lead hydroxide was expected.In 1964 it was believed that such a simple compound did not exist, as lead basic carbonate (2PbCO 3 Lead(II) hydroxide, Pb(OH) 2, is a hydroxide of lead, with lead in oxidation state +2.
