As I remember, you can dose Benzidine in an aqueous acidic solution of your analyte.
In this manner, a type of chemical reactants like oxidizers (for example, nitrates, chlorates) run a chemical reaction in acidic media, so benzidine becomes its oxidized and coloured form.
This new coloration highlights you have a strong oxidizer.
If your analyte contains nitrate salts you see a strong hue by means of well-known Lunge's essays for nitrates.
I hope this helps you.

Offhand, I can't remember what reactions Benzidine was used as an indicator for.
What I can remember is that it is a potent carcinogen, and the use of benzidine is now banned for most purposes in many countries. There are many less harmful alternatives that can be used instead.
