Mixed ligand complex formation of nicke(II),copper(II) and zinc(II) with some amino acids and imidazoles

850-853Proton-ligand stability constants for the amino acids viz., aspartic acid and glutamic acid and three imidazolcs, viz., imidazole, 2-methylimidazole and 2-ethylimidazole, hydrlytic constants for the metal ions (Cu2+, Ni2+ and Zn2+) and the stability constants for fifteen binary complexes and eighteen ternary complexes of these metal ions and ligands have been determined by <span style="font-size:12.0pt;font-family:"Times New Roman","serif";mso-fareast-font-family: Calibri;mso-fareast-theme-font:minor-latin;color:#606060;mso-ansi-language: EN-IN;mso-fareast-language:EN-US;mso-bidi-language:AR-SA">p<span style="font-size:12.0pt; font-family:" times="" new="" roman","serif";mso-fareast-font-family:calibri;="" mso-fareast-theme-font:minor-latin;color:#3c3c3c;mso-ansi-language:en-in;="" mso-fareast-language:en-us;mso-bidi-language:ar-sa"="">H-metric measurements in aqueous solutions at :30°C in 0.2M NaNO3.
