Protolytic Equilibria and Density of Solutions of Weak Electrolytes

摘要

Densimetry is a conventional method for studying solutions and, in particular, solvent—solvent and solvent—solute interactions [ 1]. In this work, we study the potential of this method for the quantitative investigation of protolytic equilibria of solutions of weak organic acids and bases. We have previously shown [2] that, within the model of infinitely diluted solutions, the observed molar volume V of a solute can be expressed as
