In the laboratory the gas may be prepared by reducing sulfuric acid (H 2 SO 4) to sulfurous acid (H 2 SO 3 ), which decomposes into water and sulfur dioxide, or by treating sulfites (salts of sulfurous acid) with strong acids, such as hydrochloric acid, again forming sulfurous acid. Ammonia and sulfuric acid combine to form ammonium sulfate. After days of heating up litres of stagnant pee, Hennig managed to isolate a white, waxy solid, which was probably something of a disappointment after his long and olfactorily-challenging work. Phosphorus trichloride is also a very important and necessary industrial chemical and hence is used in manufacture of other important chemicals. The decomposition may be accelerated by metallic catalysts like Nickel, Iron. In an excess of oxygen, the product will be almost entirely phosphorus(V) oxide.
