Color change in redox reactions
WebIdentify redox reactions by changes in oxidation state and by the colour changes involved when using acidified potassium manganate(VII), and potassium iodide. Oxidation state An oxidation state is a number that is assigned to an element in a chemical compound. This number represents the number of electrons that an atom has gained, lost, or ...
