Preparation of a pure, dry sample of a soluble salt from an insoluble oxide or carbonate using a Bunsen burner to heat dilute acid and a water bath or electric heater to evaporate the solution.
Determination of the reacting volumes of solutions of a strong acid and a strong alkali by titration.
Investigate what happens when aqueous solutions are electrolysed using inert electrodes.
Investigate the variables that affect temperature change in chemical reactions eg acid plus alkali.
Investigate how changes in concentration affect the rates of reactions by both measuring the volume of a gas produced and monitoring a change in colour or turbidity.
Investigate how paper chromatography can be used to separate and tell the difference between coloured substances. Students should calculate Rf values.
