Chemistry Required Practicals

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 changes in reacting solutions such as, eg acid plus metals, acid plus carbonates, neutralisations, displacement of metals.

Investigate how changes in concentration affect the rates of reactions by a method involving measuring the volume of a gas produced and a method involving a change in colour or turbidity.

Investigate how paper chromatography can be used to separate and tell the difference between coloured substances and calculate Rf values.
