Abstract

Solutions of various concentrations of tetramethylammonium chloride and trimethylammonium chloride in liquid hydrogen chloride have been examined by Raman spectroscopy and the solvation number of Cl^−^ anions in these solutions determined. It was found for solutions up to 3 mol I^−1^ of (CH~3~)~4~N^+^Cl^−^ in liquid HCl, that the Cl^−^ anions are solvated by six HCl molecules, while trimethylammonium chloride exists in the form of ion pairs solvated by five HCl molecules, (CH~3~)~3~N^+^H ⃛Cl^−^, 5HCl.
