Lesson 9 - Neutralisation
Learning Intentions:
Today we will be learning how to neutralise an acid
or alkali.
Success Criteria:
 I can describe how to neutralise an acid or alkali.
 I can explain real life examples of neutralisation.
Starter – Match up
Experiment
Aim:
To find out what happens to the pH when you mix
equal quantities of acid and alkali.
Results:
Acid pH
Alkali pH
Solution
pH

Experiment part 1
Method:
1. Add 1 drop of acid (hydrochloric acid) and
alkali (sodium hydroxide) to a dimple tray.
2. Test the pH. What colour is it?
Experiment part 2
1. Add 10cm3 of acid (hydrochloric acid) and
alkali (sodium hydroxide) to an evaporation basin.
2. Evaporate the liquid – what are you left with?
Turn Bunsen
Burner off when
you only have a
little liquid left.
Neutralisation
Neutralisation is when an acid reacts with an alkali
to form a neutral solution of a salt + water.
Conclusion:
Acid + Alkali  Neutral Solution: salt & water
hydrochloric acid+ sodium hydroxide sodium chloride + water
