Summary
Chemical reaction and explanation for TNTplus nitrogen ammonia reagents
Answer
In each nitrogen-ammonia method there is a "Summary of method" section. This section details the chemistry explanation and reactions that occur using the reagent set. The nitrogen-ammonia TNTplus Methods 10205 uses salicylate and has the following chemical reaction:
Ammonium ions react at pH 12.6 with hypochlorite ions and salicylate ions in the presence of sodium nitroprusside as a catalyst to form indophenol. The amount of color formed is directly proportional to the ammonia nitrogen present in the sample.
