ExperimentPreparing a soluble salt by neutralisation
Ammonia and sulfuric acid react to form ammonium sulfate, which can then be recovered by crystallisation.

Experiment
Thermal decomposition of metal carbonates
Use this class practical to compare the thermal stabilities of carbonates of reactive and less reactive metals. Includes kit list and safety instructions.
-
Experiment
Where does carbon come in the reactivity series?
The position of carbon in the reactivity series is determined by heating carbon with metal oxides and looking for evidence of a reaction.

Experiment
Electrolysis of copper(II) sulfate solution
Explore the electrolysis of copper(II) sulfate solution and related industrial processes with this class experiment. Includes kit list and safety instructions.

Experiment
The pH scale
The pH of a substance can be found by dissolving a small amount of the substance in deionised water and adding a few drops of Universal Indicator solution. The colour produced is compared with a pH chart.

Experiment
Catalysis of the reaction between zinc and sulfuric acid
Compare the rate of reaction between zinc and sulfuric acid with copper as a catalyst in this simple class practical. Includes kit list and safety instructions.
-
Experiment
Detergents, soaps and surface tension
A series of brief experiments on the effects of detergents and soaps on the surface tension of purified and hard water. Includes kit list and safety instructions.

Experiment
Making soaps and detergents
Castor oil, a source of vegetable oils, reacts with a concentrated alkali to form soaps. Or, it reacts with concentrated acid to form a detergent.

Experiment
Making a pH indicator
A pH indicator is a substance that has a different colour when added to acid or alkali. In this experiment a pH indicator is made from red cabbage.
