Both reaction b and reaction d are combustion reactions, although with different oxidizing agents. In disproportionation reactions, a single substance can be both oxidized and reduced. These are known as disproportionation reactions, with the following general equation:.

Disproportionation reactions do not need begin with neutral molecules, and can involve more than two species with differing oxidation states but rarely. This a decomposition reaction of hydrogen peroxide, which produces oxygen and water.

Oxygen is present in all parts of the chemical equation and as a result it is both oxidized and reduced.

The reaction is as follows:. You can confirm that by identifying the oxidation states of each atom in each species. Rules for Assigning Oxidation States The oxidation state OS of an element corresponds to the number of electrons, e - , that an atom loses, gains, or appears to use when joining with other atoms in compounds.

In determining the oxidation state of an atom, there are seven guidelines to follow: The oxidation state of an individual atom is 0.

The total oxidation state of all atoms in: a neutral species is 0 and in an ion is equal to the ion charge. Because sodium phosphite is neutral species, the sum of the oxidation numbers must be zero. The ion has a charge of -1, so the sum of the oxidation numbers must be
