In this process, ammonium bi-sulfate is formed first. Heating at higher temperatures causes it to decompose into ammonia, nitrogen, sulfur dioxide, and water. Ammonium sulfate solution is acidic as a salt of a strong acid (sulfuric acid) and a weak base (ammonia). A solution of 0.1 mm is equal to 5.5.
