Stability of Complexes of Several Carboxylic Acids Formed with Bivalent Metals

Abstract

Abstract Stability constants of the bivalent metal complexes formed with several mono- and dicarboxylic acids were determined at 25°C and ionic strength of 0.1. For monocarboxylic acids and several dicarboxylic acids having no double bond or forming larger chelate rings than six membered rings the following stability order held: Pb>Cu>Cd>Zn>Ni. It is very remarkable that lead showed the highest stability among bivalent metals.
