Abstract

The hydrolysis of trimethyltin(IV) has been studied by potentiometry (H⁺ -glass electrode) and calorimetry in various salt media (NaNO₃, NaCl, KCl, Na₂SO₄, and NaNO₃-NaCl mixtures). The effect of ionic strength on the hydrolysis constants is accounted for by a simple Debye-Huc̈kel type equation and by Pitzer equations. The results allow us to obtain ΔH for hydrolysis and the temperature dependence of the Pitzer parameters. The resulting coefficients can be used to examine the speciation of (CH₃)₃Sn⁺ in multicomponent electrolyte solutions, such as natural waters, over a wide range of temperature and ionic strength.
