Study of hydrolytic kinetics of the hexachlorostannate anion by two-dimensional 119 Sn exchange spectroscopy.

ABSTRACT

Two-dimensional 119 Sn exchange spectroscopy was applied to study the hydrolytic kinetics of the hexachloro-stannate anion, SnCl6 2- . Two 119 Sn exchange spectra for SnCl4 · 5H2 O solutions with various HCl concentrations are presented. Magnetization exchanges, which are related to the hydrolysis processes, occur in the SnCl6 2- hydrolysis series. The exchange rate constants, the hydrolysis rate constants and the hydrolysis equilibrium constants were evaluated.
