| Abstract: | The redox properties of heteropolytungstates KnMW11O39Ni(H2O)] .xH2O (M= Si, Ti,Ga,Zr) in solution are studied with polarography and cyclic voltammetry, together with ultraviolet spectroscopy and X-ray photoelectron spectroscopy. The order of polarographic half-wave potential (E1/2) of heteropoly anious is as follows; Zr>Ti>Ga>Si. We have found that the E1/2 of heteropoly anious could corelate linearly with the eletronetivities of M. |
