Solvent Effects on Protonation and Complexation of Histidine with Molybdenum(VI) in Different Aqueous Solutions of Methanol

The formation constants of the species formed in the systems H++ Mo(VI) + histidine and H++ histidine have been determined in different aqueous solutions of methanol (۰-۴۰ % v/v) at ۲۵ C and constant ionic strength (۰.۱ mol dm-۳ sodium perchlorate), using a combination of spectrophotometric and potentiometric techniques. The composition of the complexes was determined by the continuous variations method [۱-۲].
