Abstract The acid dissociation constants of nine aliphatic carboxylic acids in several N,N-dimethylformamide-water mixtures were subjected to factor analysis (FA) and two solvent factors emerged. A further target factor analysis (TFA) indicated that the Kamlet and Taft general equation is reduced in these mixtures to two terms: the independent one and that related to the hydrogen bond acceptor (HBA) basicity β solvatochromic parameter. Accordingly, an excellent correlation is found between the logarithmic values of the acidity constants of each acid in the binary mixtures and their corresponding β values.
