To test for the presence of nitrite ions, you can use the Griess test. This involves adding sulfanilic acid and N-1-naphthylethylenediamine dihydrochloride to the solution containing nitrite ions, which will produce a pink color if nitrite ions are present. Another method is using a diphenylamine reagent, which will turn blue in the presence of nitrite ions.
The process is called nitrification, where ammonia is first converted to nitrite by bacteria called Nitrosomonas, and then to nitrate by bacteria called Nitrobacter.
