Reactions in mixed non-aqueous systems containing sulphur dioxide. Part 3. The electrolytic dissolution of metals

Abstract

The metals Mg, Cr, W, Fe, Ni, Cu, Zn, Hg, AI, Sn, and Pb dissolve electrolytically in the mixed non-aqueous solvents sulphur dioxide–dimethyl sulphoxide, –dimethylformamide, –acetonitrile, –acetone, or –nitrobenzene to form solutions containing several sulphur anions. Reactions of the metals Mg, Cr, Fe, Cu, and Zn with dimethyl sulphoxide-sulphur dioxide give pure single products of metal disulphates. The relationship of solvent parameters to metal reactivity is discussed.
