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 .
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 ...
Crystalline potassium permanganate (KMnO 4) is placed in an evaporating dish. A depression is made at the center of the permanganate powder and glycerol liquid is added to it. The white smoke-like vapor produced by the reaction is a mixture of carbon dioxide gas and water vapor.
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.

A permanganate (/ p ər ˈ m æ ŋ ɡ ə n eɪ t, p ɜːr-/) [1] is a chemical compound with the manganate(VII) ion, MnO − 4, the conjugate base of permanganic acid.Because the manganese atom has a +7 oxidation state, the permanganate(VII) ion is a strong oxidising agent.
Unfortunately, another male’s reaction is instant aggression, which can lead to a fight among the males. When males release their scent, they aren’t only letting the female lemurs know they ...
Morgan said that while her mother was in high school, hot Dr Pepper was the go-to warm drink at concession stands. When her mom made the drink for her, she instantly loved it.
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.
