Warm concentrated potassium permanganate (KMnO 4) will react with an alkene to form a glycol. Following this dihydroxylation , the KMnO 4 can then cleave the glycol to give aldehydes or ketones. The aldehydes will react further with (KMnO 4 ), being oxidized to become carboxylic acids .
The exothermic (heat producing) reaction between potassium permanganate (KMnO 4), a strong oxidizing agent, and glycerol (C 3 H 5 (OH) 3), a readily oxidised organic substance, is an example of an experiment sometimes referred to as a "chemical volcano". [7] [8]
Addition of concentrated sulfuric acid to potassium permanganate gives Mn 2 O 7. [76] Although no reaction may be apparent, the vapor over the mixture will ignite paper impregnated with alcohol. Potassium permanganate and sulfuric acid react to produce some ozone, which has a high oxidizing power and rapidly oxidizes the alcohol, causing it to ...
The chemical chameleon reaction shows the process in reverse, by reducing violet potassium permanganate first to green potassium manganate and eventually to brown manganese dioxide: [1] [2] [5] KMnO 4 (violet) → K 2 MnO 4 (green) → MnO 2 (brown/yellow suspension) Blue potassium hypomanganate may also form as an intermediate. [6]
The exact chemical reaction depends on the carbon-containing reactants present and the oxidant used. For example, trichloroethane (C 2 H 3 Cl 3) is oxidised by permanganate ions to form carbon dioxide (CO 2), manganese dioxide (MnO 2), hydrogen ions (H +), and chloride ions (Cl −). [3] 8 MnO − 4 + 3 C 2 H 3 Cl 3 → 6 CO 2 + 8 MnO 2 + H ...

Potassium permanganate will decompose into potassium manganate, manganese dioxide and oxygen gas: 2 KMnO 4 → K 2 MnO 4 + MnO 2 + O 2. This reaction is a laboratory method to prepare oxygen, but produces samples of potassium manganate contaminated with MnO 2. The former is soluble and the latter is not.
