Hammett acidity function in concentrated aqueous solutions of hydrochloric acid–lithium chloride

Abstract

The Hammett acidity function in hydrochloric acid–lithium chloride aqueous solutions, at 25·0 °C has been measured at various ionic strengths (µ). The H₀-value is very sensitive to the ionic strength. H₀+ log C_H+ is not a constant but a plot thereof against C_H+(at constant ionic strength) is linear and a set of such plots, for different µ-values, are parallel. At a given acid concentration: H₀=Lµ+ constant (the constant is almost zero). Other relationships are presented and discussed.
