Institution:Department of Chemistry, Ravenshaw College, Cuttack India
Abstract:From the measurements of conductivity, diffusion coefficient etc., Jander indicated the presence of several isopoly-anions of molybdenum under different pH conditions. He and subsequent workers in the field dealt with solutions only. In the present work one free molybdic acid, and one ammonium acid molybdate were isolated in solid condition at pH 4.6 and 2. On analysis, their compositions were found to be H4Mo3O11 and NH4H5Mo6O21 (or (NH4)2H4Mo7O24) respectively.
