Neutralisation

Neutralisation of Acids

Acids are neutralised by bases (a base is an alkali that dissolves in water). Metal carbonates, metal oxides and metal hydroxides are all examples of bases.

Metal carbonates

Acid + carbonate → salt + water + carbon dioxide.
- E.g. hydrochloric acid + calcium carbonate → calcium chloride + water + carbon dioxide

Metal oxides

Acid + oxide → salt + water.
- E.g. hydrochloric acid + magnesium oxide → magnesium chloride + water.

Metal hydroxides

Acid + hydroxide → salt + water.
- E.g. hydrochloric acid + sodium hydroxide → sodium chloride + water.
