Classic Chemistry Experiments : An oxidation and reduction reaction


A conical flask contains a colourless solution. When shaken, a blue colour forms. After a few seconds, the blue colour fades and the solution again becomes colourless. The process can be repeated. It is an oxidation followed by a reduction process.


This experiment is one of a collection of 100 experiments in a book called Classic Chemistry Experiments. You can buy a copy via the Royal Society of Chemistry online shop for £27.50.
