Coupling of Diazonium salt of Sulphanilic acid with N,N-dimethylaniline
The coupling reaction of diazonium salt of sulphanilic acid with N,N-dimethylaniline is an important reaction in organic chemistry. This reaction is used to obtain a dye that is used as an indicator in various chemical reactions.
Methyl Orange as an Indicator
Methyl orange is the indicator that is obtained by coupling the diazonium salt of sulphanilic acid with N,N-dimethylaniline. Methyl orange is an azo dye, and it is used as an indicator in acid-base titrations. This indicator changes color from red to yellow as the pH of the solution changes from acidic to basic.
Working of Methyl Orange
The working of methyl orange is based on the principle of acid-base reactions. In acidic solutions, the dye exists in a red form, which is protonated. In basic solutions, the dye exists in a yellow form, which is deprotonated. The red and yellow forms of the dye have different absorption spectra, which makes it possible to distinguish between acidic and basic solutions.
Conclusion
Methyl orange is a commonly used indicator in chemistry, and it is obtained by coupling the diazonium salt of sulphanilic acid with N,N-dimethylaniline. This indicator changes color from red to yellow as the pH of the solution changes from acidic to basic.
