Potentiometric study of the hydrolysis of (CH3)Hg+ in NaClO4: construction of a thermodynamic model

Abstract: The hydrolysis of CH 3 Hg was studied potentiometrically in NaClO 4 media in the range 0.1-3.0 mol dm À3 ionic strength at 25°C. Evaluation of data with the non-linear least-squares computer programs BSTAC and STACO led us to propose the formation of CH 3 HgOH and (CH 3 Hg) 2 OH species. The stoichiometric stability constants obtained for the two species at the different ionic strengths were correlated by means of Modified Bromley Methodology (MBM) to obtain the corresponding thermodynamic equilibrium constant… Show more
