[ad. F. plombite (E. Fremy 1843, in Jrnl. de Pharm. III. 31), f. plomb lead: see -ite1.]
Any of various (salts of) oxyanions or hydroxy anions of bivalent lead, which are formed esp. by the action of alkalis on lead(ii) hydroxide and are freq. represented as PbO22-; applied also to certain mixed oxides of bivalent lead and another metal.
1851H. Watts tr. Gmelin's Hand-bk. Chem. V. 158 (heading) Plumbite of ammonia. 1903H. C. Jones Princ. Inorg. Chem. xl. 480 Lead hydroxide..has..acid properties dissolving readily in strong bases. The salts have the composition M2PbO2 and are known as plumbites. 1927J. W. Mellor Comprehensive Treat. Inorg. & Theoret. Chem. VII. xlvii. 665 The plumbites all appear to be salts of a monobasic acid analogous with the corresponding stannites and germanites. Ibid. 669 Grube obtained a mixture, 2MgO.PbO.3H2O, or magnesium plumbite, by the oxidation of magnesium hemiplumbide in the presence of moisture. 1950N. V. Sidgwick Chem. Elements & Compounds I. 603 It is possible to make a plumbate by atmospheric oxidation of a plumbite. 1968K. M. & R. A. Mackay Introd. Mod. Inorg. Chem. xv. 223/1 Addition of alkali to lead II solutions gives a precipitate of the hydrated oxide, which dissolves in excess alkali to give plumbites. |
