The two theories that explain the acid-base indicator are Ostwald's theory and the quinonoid theory.
Because it changes color at the pK a of a mid strength acid, it is usually used in titration for acids.

    Methyl orange's production and use as a pH indicator and as a dye for textiles may result in its release to the environment through various waste streams. The ionic state of methyl orange makes this compound essentially non-volatile, therefore methyl orange should exist solely in the particulate phase in the ambient atmosphere.

    The litmus colour change happens over an unusually wide range, but it is useful for detecting acids and alkalis in the lab because it changes colour around pH 7. Methyl orange or phenolphthalein would be less useful. This is more easily seen diagramatically. For example, methyl orange would be yellow in any solution with a pH greater than 4.4.
