Redox reactions

Corrosion

Gradual destruction of materials by chemical reaction with its environment

Disproportionation

Redox reaction in which a chemical species of intermediate oxidation state is converted into two different species of higher and lower oxidation states

Half-reaction

Redox reaction component

Oxidation state

Number that describes the degree of oxidation of an atom in a chemical compound; the hypothetical charge that an atom would have if all bonds to atoms of different elements were fully ionic

Oxidizing agent

Chemical compound used to oxidize another substance in a chemical reaction

Redox

Chemical reaction in which oxidation states of atoms are changed

Reducing agent

Element or compound that loses (or "donates") an electron to another chemical species in a redox chemical reaction

Rust

Type of iron oxide

Tarnish

Corrosion on outer layer of some metals
