| Three categories that encompass all these different redox reactions are atom transfer redox reactions, electron transfer reactions, and disproportionation reactions. |
| A reaction in which the same element is both oxidized and reduced is called a disproportionation reaction. |
| The disproportionation of chlorine dioxide to chlorate and chlorite in aqueous solution is very slow. |
| It has been shown above that sulphur disproportionation was probably active in the basin, allowing for a higher fractionation between sulphates and sulphides. |
| The net differences in the entropy term of the disproportionation equilibria are small, which may reflect cancellations of components rather than lack of interactions. |
| Reactions in which atoms of the same element are both oxidized and reduced are disproportionation reactions. |
