Abstract

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.
