Inorganic nitrogen transformations result from the chemical oxidation and reduction of sulfur compounds. In the reduction of nitrate by NaHS, Na 2 S 2 O 4 in both acidic and basic solutions, nitrite was not obtained suggesting that it may not be one of the major intermediate products in such reductions. Hydroxylamine was one of the intermediate products in the reduction of nitrite in acidic solution. Ammonia was not produced appreciably in the reduction of nitrate and nitrite. Due to the interference of hydroxylamine with Nessler reagent, ammonium ion formed in the reduction of hydroxylamine by sulfur compounds could not be measured quantitatively. However, a larger amount of ammonium‐N in the reduction of hydroxylamine by H 2 SO 3 was observed. Nitrite, hydroxylammonium, and ammonium ions were never found in the solution in large quantities presumably due to (i) the formation of H 2 N 2 O 2 which is unstable with respect to the formation of N 2 O (1,2), (ii) the interaction between nitrite and hydroxylammonium ions in the formation of N 2 O (1,3), and (iii) the oxidation of hydroxylamine or hydrazine by sulfur compounds to form N 2 O and N 2 .
