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 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]
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.
Reagents are "substances or compounds that are added to a system in order to bring about a chemical reaction or are added to see if a reaction occurs." [1] Some reagents are just a single element. However, most processes require reagents made of chemical compounds. Some of the most common ones used widely for specific reactive functions are ...
A hairdo like the Komondor’s comes with a considerable grooming burden. Their long, corded coats require regular grooming, and every so often the coat clumps up and needs time-consuming separation.

The basic chemical reaction involved in the Hummers' method is the oxidation of graphite, introducing molecules of oxygen to the pure carbon graphene. The reaction occurs between the graphene and the concentrated sulfuric acid with the potassium permanganate and sodium nitrate acting as catalysts.
