Dissociation of 2,4-Dinitrobenzoic Acid and D-10-Camphosulfonic Acid in Water-Methanol Mixtures at 25 °C

Abstract

The dissociation constants and the equivalent conductances of 2,4-dinitrobenzoic acid and D-10-camphosulfonic acid have been determined in water-methanol mixtures at 25 °C. The experimental data have been analyzed with the “Fuoss 78” conductance equation. The Bjerrum critical distance was accepted instead of Gurney’s cosphere diameter. Values of K_A and Λ₀ are reported.
