Fifteen azo dyes containing a hydroxy group, phenol, 1-naphthol and 2-naphthol were titrated potentiometrically with tetrabutylammonium hydroxide (TBAH) at room temperature. Potentiometric titration curves of these compounds in acetonitrile with TBAH propan-2-ol-methanol are similar to those ofweak acids obtained in aqueous media with strong bases. Acetonitrile is a suitable medium for the weakly acidic compounds titrated in this work.
