What you'll learn
Acids and alkalis, how indicators show acidity, the pH scale as a conceptual acidic-to-alkaline range, neutralisation, and the signs that tell you a chemical reaction has happened.
- Acids and alkalis are everyday substances
- Indicators change colour to show acidity
- The pH scale runs acidic to alkaline
- Neutralisation: acid + alkali makes salt and water
- Metals and carbonates react with acids differently
- Chemical reactions show recognisable signs
