In this study, the pK a values of some azo dyes derived from cyclohexane-1,3-dione in different organic solvent + water mixtures have been determined spectrophotometrically. The organic solvents used are ethanol, acetone and N,N-dimethylformamide (DMF). Thus, the nature and the proportion of the org
