Abstract
Abstract Pyridine-2-azo- p -dimethylaniline is suggested as an indicator in the titration of amines (aniline, butylamine, p -phenylenediamine and ethylenediamine) with perchloric acid in glacialacetic acid medium. The precision obtainable is much better than that with crystal violet indicator. The pyridine dye can also be used satisfactorily in the titration of sodium carbonate and sodium acetate.
