At a time when light was usually produced by burning something, Hennigs discovery was source of great curiosity, and it was hoped that phosphorus might offer a safer alternative to candles for lighting the home. Sulfur trioxide decomposes into sulfur dioxide and oxygen in an equilibrium. 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.
