强电解质混合溶剂体系的电导法分析

摘要/Abstract

摘要： 在生产和科研中经常需要同时测定强电解质浓度和混合溶剂的比例。本文在研究强电解质+水+醇三元溶液电导特性的基础上,建立了两参数经验性电导工作方程,将溶液电导率的测量与电导滴定相结合,可以方便准确地定出此类三元溶液的组成。

Abstract: The following emperical expression was derived from the measurement of electrocon-ductivity x of HCl+H₂O+CH₃OH at 25℃ in the range of 0.002< m_MHC1 <0.05 and 0.2< W_H₂O <1 (W_H₂O, grams H₂O/grams solvent), x=[A₀+A₁(W_H₂O^1.5expW_H₂O-0.7W_H₂O²)]m_MHC1+10^-5 This expression is capable of representing the conductance of a strong 1—1 electrolyte in various alchoholic aqueous solutions. By measuring the conductivity of the solution,analyzing the molarlity of the electrolyte through conductometric titration the composition of the solution can be conveniently determined with certain accuracy.
