Abstract
Abstract The project deals with the determination of ionization constants Ka for ten acidic compounds derived from benzoyl acetone and dimedone by conductivity method in water and ethanol solvents. These acids are in forms of monoxime, dioxime and phenolic Schiff bases. The calculated relative constants Kr for each acid are obtained by dividing the ionization constant in ethanol by its value in water and at constant temperatures. The Kr values collected have less than unity. A direct linear plots are obtained between pKa for any acid versus the dielectric constant of ethanol at the five different temperatures. The results are discussed in detail.
