1. Lesson Starter
Explain what happens to the colour and pH of an acid if alkali is added
Describing neutralisation reactions
Everyday neutralisations

2. Learning Intention
To learn about neutralising acids by carrying out an ACCURATE neutralisation reaction.

3. Recap

4. Experiment
Pour acid into a beaker and use syringe to measure 10 mls of acid- add to boiling tube
Add a couple of drops of universal indicator to the boiling tube
Pour alkali into beaker and use second syringe to measure 10 mls
SLOWLY add 1 ml of alkali to boiling tube and swirl- note colour of solution
Repeat until colour of solution in boiling tube is green

6. All acids and alkalis are harmful

7. The more concentrated an acid is, the closer to 0 it will appear on the pH scale

8. Corrosive alkalis are close to 7 on the pH scale

9. Lemon juice, coke and vinegar are all examples of household acids

10. Brushing our teeth is an example of a neutralisation reaction

11. During neutralisation, the pH of a solution always gets higher
