Water is decomposed into hydrogen and oxygen by reacting it with iodine and sulfurous acid to produce hydrogen iodide and sulfuric acid. The hydrogen iodide is decomposed to produce the hydrogen product and the iodine. The sulfuric acid is decomposed to produce water and sulfur trioxide. The sulfur trioxide is decomposed to produce sulfur dioxide and the oxygen product. The sulfur dioxide is reacted with water to produce the sulfurous acid.

Decomposition of water

Water is decomposed into hydrogen and oxygen in a series of steps. In the first step hydrogen sulfide is reacted with cuprous sulfide to produce the hydrogen and cuprous sulfide. The cupric sulfide is then decomposed to produce sulfur and to regenerate the cupric sulfide. The sulfur is reacted with water to produce the hydrogen sulfide and sulfur dioxide. The sulfur dioxide is reacted with water to produce sulfuric acid. The sulfuric acid is decomposed to produce the sulfur dioxide, oxygen, and water. The decomposition of the sulfuric acid can be performed in four steps. In the first step the sulfuric acid is reacted with a metallic oxide to produce a solution of a metallic sulfate. The hydrate of the metallic sulfate is crystallized from the solution and is decomposed into the metallic sulfate and water. The metallic sulfate is decomposed into the metallic oxide, oxygen, and the sulfur dioxide.
