Cathodic action of lead malate complexes at the dropping mercury electrode

Abstract

The electrode reduction reaction of lead malate, involving deprotonated malate ion and a proton, between pK₁ and pK₂ values of the acid has been investigated. At pH < pK₁ protonated ion participates and a proton is involved. The effect of ligand concentration on the half-wave potential of Pb²⁺ has been investigated and the stability constants of species so formed computed.
