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

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
