Nessler's reagent A for determination of nitr

Determination of ammonium/nitrogen salts using mercury containing materials. The classical colorimetric detection and determination of ammonium salts is carried out using Nessler's reagent- a yellow colour indicative of ammonium salts. A more recent development of the technique is to use a 2-bottle system to prepare fresh reagent for each use.
