- Neutralization
- A chemical reaction happens if
you mix together an acid and a
base. The reaction is called
neutralisation, and a neutral
solution is made if you add just
the right amount of acid and
base together
- Reasons for neutralization
- Farmers use lime (calcium
oxide) to neutralise acid soils.
- Your stomach contains
hydrochloric acid, and too much of
this causes indigestion. Antacid
tablets contain bases such as
magnesium hydroxide and
magnesium carbonate to neutralise
the extra acid.
- Bee stings are acidic. They can be neutralised using baking
powder, which contains sodium hydrogen carbonate.

- Reacting with metals
- Acids react with most metals and a salt is produced.
But unlike the reaction between acids and bases we
don't get any water. Instead we get hydrogen gas.
