GCSE level easier m/c QUIZ on pH, Indicators, Acids, Bases, Neutralisation and Salts

GCSE level harder m/c QUIZ on pH, Indicators, Acids, Bases, Neutralisation and Salts

pH scale Acids, Bases and Salts Revision NOTES INDEX

1. Everyday examples of acids, alkalis, salts, pH of solution, pH scale, hazard warning signs

2. pH scale, indicator colours, ionic theory of acids, alkalis (bases) & neutralisation

3. Examples of acid, neutral or alkaline solutions (now included in section 1. above)

4. Acid reactions with metals/oxides/hydroxides/carbonates/ammonia, neutralisation to give salts

(Part 4 includes redox half equations for the metal-acid reaction and how to work out the formula of a salt given the constituent ions, both needed for higher level GCSE courses)

5. More on reactions of bases-alkalis like ammonia and sodium hydroxide (overlaps with Part 4.)

6. Methods of making salts index and chemical tests for ions in salts & tests for common gases

7. Changes in pH in a neutralisation reaction, choice and use of indicators

8. Important formulae, salt solubility and water of crystallisation

9. Further examples of equations now included in sections 4, 5 and 6

10. More on acid-base theory - weak and strong acids and their properties
