| Abstract: | Speciation of Co(II), Cu(II) and Zn(II) complexes of L-glutamic acid has been studied in varying concentrations (0-36.83% w/w) of urea solutions maintaining an ionic strength of 0.16 mol dm-3 at 303 K. The protonation and formation constants are refined with the computer program, MINIQUAD75 using the primary alkalimetric data. Selection of the best fit chemical models is based on statistical parameters and residual analysis. The trend in variation in values of the protonation and the metalligand stability constants with the dielectric constant has been explained on the basis of electrostatic and non-electrostatic forces. |
