Hyponyms (each of the following is a kind of "chemical reaction"):
addition reaction (a chemical reaction in which one molecule is added to another)
reducing; reduction (any process in which electrons are added to an atom or ion (as by removing oxygen or adding hydrogen); always occurs accompanied by oxidation of the reducing agent)

oxidation-reduction; oxidoreduction; redox (a reversible chemical reaction in which one reaction is an oxidation and the reverse is a reduction)
oxidation; oxidisation; oxidization (the process of oxidizing; the addition of oxygen to a compound with a loss of electrons; always occurs accompanied by reduction)
neutralisation; neutralisation reaction; neutralization; neutralization reaction (a chemical reaction in which an acid and a base interact with the formation of a salt; with strong acids and bases the essential reaction is the combination of hydrogen ions with hydroxyl ions to form water)
