Abstract
The p
and p
values of maleic and malonic acids were determined by using a precise EMF method in acetone–water media of varying solvent compositions at different temperatures. The thermodynamic functions of dissociation (Δ
°, Δ
°, and Δ
°) have been computed, discussed and analyzed in terms of solute–solvent interactions. The p
values have been correlated with both the mole fraction of the organic solvent and the distance between the dicarboxyl groups in each acid.
