Demonstrate in-depth/comprehensive understanding typically involves linking aspects of acids and bases. It may involve explaining, elaborating, justifying, relating, evaluating, comparing and contrasting, or analysing. This may require the use of chemistry vocabulary, symbols and conventions (including names and formulae), and writing balanced symbol equations.
Aspects of acids and bases will be selected from:
Electron arrangement of atoms and monatomic ions of the first 20 elements (a Periodic Table will be provided).
Ionic bonding.
Names and formulae of ionic compounds using a given table of ions.
Particle theory and Collision theory
Measuring Reaction Rates, either from reactants or products
Factors affecting the rates of a reaction
Acids release hydrogen ions in water.
Reactions (of acids with bases) to form salts.
pH and effects on indicators.
Neutralisation.
Carbon dioxide formation.
Salt formation.
Notes:
Acids and bases are restricted to HCI, H2SO4, HNO3, metal oxides, hydroxides, carbonates and hydrogen carbonates. Other acids may be included in examination questions. The names and formulae of any such acids will be given in the question.
