-
ExperimentThe effect of temperature on reaction rate
Discover more about collision theory in this practical, where a sodium thiosulfate and hydrochloric acid mixture produce an interesting reaction. Includes kit list and safety instructions.
-
ExperimentThe effect of concentration on reaction rate
Students react sodium thiosulfate solution is reacted with acid – a sulfur precipitate forms. The time taken for a certain amount of sulfur to form can be used to indicate the rate of the reaction. Contains kit list and safety instructions.
-
ExperimentCorrosion in different atmospheric conditions
Try this practical to test the corrosion of metals in dry air, moist air and air polluted by acidic sulfur dioxide. Includes kit list and safety instructions.
