基于副反应形成配合物浓度的计算公式及应用
A Formula for the Calculation of Complex Concentrations Arising from Side Reactions and Its Applications
摘要
Abstract
In complexometric titration,ethylenediaminetetraacetic acid(EDTA),commonly referred to as Y,is the titrant of choice.This system often encompasses various side reactions.This paper derives a formula at the stoichiometric point,based on the side reaction coefficient(α),for calculating the concentration of NY or ML coordination compounds with a coordination ratio of 1:1,where NY represents the complex of ligand Y with coexisting metal ions(Nn+),and ML denotes the complex of the target metal ions(Mn+)with other ligands(L).The formulation significantly streamlines the computation of these complex concentrations.关键词
