Structure of Methyl Orange
The structure of methyl orange consists of a central azo group (―N=N―), which is the characteristic feature of azo dyes. This azo group connects two aromatic rings: a benzene ring and a naphthalene ring. One of the nitrogen atoms in the azo group is protonated and carries a positive charge when the indicator is in its acidic form. The other nitrogen atom is connected to a sodium atom and a sulfonate group, which contribute to the water solubility of methyl orange. The structure of Methyl Orange is shown below:
Chemical Formula of Methyl Orange

Methyl Orange pH Range
Methyl orange is used as an indicator because of its various pH ranges. The pH range of methyl orange is 3.1 to 4.4
Methyl Orange
Methyl Orange is an azo dye which is soluble in water. It is an organic compound composed of carbon, hydrogen, nitrogen, sodium, oxygen and sulphur. Methyl Orange doesn’t react permanently with acids or bases. Its effective pH value ranges from pH 3.1 to pH 4.4. Methyl orange is not similar to litmus paper because methyl orange has a very low range compared to litmus. Methyl orange doesn’t have a full spectrum of colors.
