Popis:	The ionisation constants of N-0-tolyl-p-substituted benzohydroxamic acids have been determined in 10-70% v/v dioxane-water media at 25 and 35±0.1°C. The pKa's in aqueous media (at 10% dioxane) have been obtained using the method of extrapolation and least squares. The pKa values vary linearly with the mole fraction of dioxane. These constants are tested for the applicability of the Hammett equation.
