What are Acids and Bases?
- Describe the meanings of the terms acid and alkali in terms of the ions they produce in aqueous solution and their effects on Universal Indicator.
- Describe qualitatively the difference between strong and weak acids in terms of the extent of ionisation
- Describe how to test hydrogen ion concentration and hence relative acidity using Universal Indicator and the pH scale.
What are the Properties of Acids and Bases?
- Describe the characteristic properties of acids as in reactions with metals, bases and carbonates.
- Describe the characteristic properties of bases in reactions with acids and with ammonium salts.
- Describe the reaction between hydrogen ions and hydroxide ions to produce water, H+ + OH– → H2O, as neutralisation.
- Classify oxides as acidic, basic, amphoteric or neutral based on metallic/non-metallic character.
Acids and Bases in Daily Use
- State the uses of sulfuric acid in the manufacture of detergents and fertilisers; and as a battery acid.
- Describe the importance of controlling the pH in soils and how excess acidity can be treated using calcium hydroxide.
