Abstract

Fits for the calculation of solvatochromic regression coefficients were done using the regression tool for the complexation of dioxovanadium(V) with iminodiacetic acid (IDA) and dissociation constants at T = 298 K and constant ionic strength of 0.1 mol dm–3 sodium perchlorate in different volume fractions of methanol (0 to 45 percent). A combination of potentiometric and UV spectrophotometric methods have been used for experimental measurements. Kamlet-Abboud- Taft (KAT)solvatochromic equation enables us to find out the contribution of various non specific and specific solute-solvent interactions. The results have been interpreted on the basis of the hydrogen-bond donor and acceptor ability and solvent polarity.
