Abstract: Although metol behaves as a very weak base in aqueous solutions, it acts as a strong base in glacial acetic acid and can be titrated with glacial acetic acid solutions of perchloric and sulfuric acids, using an indicator. The end point is much sharper with perchloric acid than with sulfuric acid as shown by potentiometric titration curves of the two acids. Procedures and results are described for the analysis of several types of developer solutions employing glacial acetic acid solutions for the metol determination and ceric sulfate for the determination of hydroquinone.
