Preparation of a Soluble Salt
Prepare a pure, dry sample of a soluble salt (copper(II) sulfate) from sulfuric acid and insoluble copper(II) oxide.
Acid-Alkali Titration
Determine the reacting volumes of solutions of a strong acid and a strong alkali by titration, calculating the concentration of one solution.
Electrolysis of Aqueous Solutions
Investigate the products formed at the electrodes during the electrolysis of different aqueous solutions using inert graphite electrodes.
Temperature Changes
Investigate the variables that affect temperature changes in reacting solutions, using the neutralisation reaction between hydrochloric acid and sodium hydroxide.
Rates of Reaction
Investigate how changes in concentration affect the rate of reaction using the sodium thiosulfate turbidity method and the magnesium-acid gas collection method.
Paper Chromatography
Investigate how paper chromatography can be used to separate and identify coloured substances, calculating Rf values.
Identifying Ions
Use chemical tests to identify cations (flame tests, sodium hydroxide precipitate tests) and anions (carbonate, halide, sulfate tests) in inorganic compounds.
Analysis and Purification of Water
Analyse water samples from different sources (pH, dissolved solids) and purify a sample using simple laboratory distillation.
