Neutralisation
Science Practicals: GCSE, topic 2.1.2
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.
