Stability constant of the trisglycinto metal complexes

Abstract

The stability constants of iron, manganese, cobalt, and nickel complexes of glycine have been determined in aqueous solution by potentiometric titration with standard sodium hydroxide solution. The values of the stepwise stability constants were obtained by ORIGIN ‘50’ program. The overall stability constants of the complexes were found to be similar.
