Complexation of molybdenum(VI) with methyliminodiacetic acid in different water plus methanol solutions

The complexation of molybdenum(VI) with methyliminodiacetic acid (MIDA) at pH 6.00, T = 298 K, I = 0.1 mol dm(-3) of sodium chloride and different water + methanol solutions (0-45 vol. %) was studied using potentiometric and UV spectrophotometric measurements. The values of the stability constants were calculated and their trends interpreted using the Kamlet-Abboud-Taft (KAT) model in order to investigate the role of different specific and non-specific interactions in aqueous solutions of methanol.
