Abstract

The dissociation constants and molar conductivities at infinite dilution of salicylic acid, 2,4-, 2,5-, and 2,6-dihydroxybenzoic acids have been determined in 1-propanol-water mixtures at 25°C. The experimental data have been analyzed by means of the Lee and Wheaton equation.

Key words  Aqueous-organic mixed solvents - conductance - Lee-Wheaton equation - 1-propanol - salicylic acid - 2,4-, 2,5-, and 2,6-dihydroxybenzoic acids
