PP093 - Iodine clock reaction: Harcourt-Essen method
Click to download Document.
The kinetics of a reaction can be investigated by determining how the rate of the reaction varies with the concentration of the reactants. The Harcourt-Essen method is useful as the reaction kinetics .. more

PP092 - Iodine clock reactions: iodide-persulfate method
Click to download Document.
Iodine clock reactions produce iodine, which reacts with starch to give the distinct blue/black colouration. The iodide-persulfate method is one of the simplest clock reactions, involving simple kinet.. more

PP091 - Iodine clock reaction: Landolt method
Click to download Document.
The Landolt method (potassium iodate(V) and sodium metabisulfite) was the first iodine clock reaction described, and can be used for a simple two-reagent investigation.

PP156 - Comparing the diffusion of halogen gases and vapours
Click to download Document.
Diffusion is direct evidence of the particulate nature of matter. There are not many demonstrations or activities for the halogens, because the gases and vapours are toxic. However, using microscale t.. more
