C+H+O compounds Each hydrogen added to a molecule can be considered as a proton plus a one-electron reduction of the redox state, while each oxygen counts as a two-electron oxidation. Thus a net addition of H2O is a simple hydration with no net change in redox state and frequently occurs reversibly in aqueous solution. These relationships may be viewed in the following table (peroxides and ions are excluded; unstable or hypothetical compounds are italicized).
