A reaction between an acid and a base. In an acid–alkali reaction, hydrogen ions react with hydroxide ions to form water.

A reaction in which an acid reacts with a base to form a salt and water. A metal carbonate also produces carbon dioxide.

A reaction in which an acid reacts with a base; an acid reacting with an alkali produces a salt and water.

A reaction between an acid and a base. In acid–alkali neutralisation, hydrogen ions react with hydroxide ions to form water.

In the hydrochloric acid–sodium hydroxide reaction, sodium ions and chloride ions remain in solution; they are not changed by the neutralisation.

In the neutralisation equation, include the charges on the ions and the state symbols: H⁺(aq), OH⁻(aq) and H₂O(l).

Do not describe an acid–metal reaction as neutralisation: it produces hydrogen, not water.
