  2. n-Butylbenzene - Wikipedia

    en.wikipedia.org/wiki/N-Butylbenzene

    Of two isomers of butylbenzene, n-butylbenzene consists of a phenyl group attached to the 1 position of a butyl group. It is a slightly greasy, colorless liquid. The synthesis of n-butylbenzene by the reaction of chlorobenzene and butylmagnesium bromide was one of the first demonstrations of the Kumada coupling using nickel diphosphine ...

  3. Glycerol and potassium permanganate - Wikipedia

    en.wikipedia.org/wiki/Glycerol_and_potassium...

    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.

  4. Reaction mechanism - Wikipedia

    en.wikipedia.org/wiki/Reaction_mechanism

    In chemistry, a reaction mechanism is the step by step sequence of elementary reactions by which overall chemical reaction occurs. [1] A chemical mechanism is a theoretical conjecture that tries to describe in detail what takes place at each stage of an overall chemical reaction. The detailed steps of a reaction are not observable in most cases.

    A stirred BZ reaction mixture showing changes in color over time. The discovery of the phenomenon is credited to Boris Belousov.In 1951, while trying to find the non-organic analog to the Krebs cycle, he noted that in a mix of potassium bromate, cerium(IV) sulfate, malonic acid, and citric acid in dilute sulfuric acid, the ratio of concentration of the cerium(IV) and cerium(III) ions ...

  6. Potassium permanganate - Wikipedia

    en.wikipedia.org/wiki/Potassium_permanganate

    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 ...

  7. Potassium manganate - Wikipedia

    en.wikipedia.org/wiki/Potassium_manganate

    Potassium manganate is the inorganic compound with the formula K 2 MnO 4. This green-colored salt is an intermediate in the industrial synthesis of potassium permanganate (KMnO 4), a common chemical. [1] Occasionally, potassium manganate and potassium permanganate are confused, but each compound's properties are distinct.

  8. Chemical chameleon - Wikipedia

    en.wikipedia.org/wiki/Chemical_chameleon

    The chemical chameleon is a redox reaction, well known from classroom demonstrations, that exploits the dramatic color changes associated with the various oxidation states of manganese. [ 1 ] [ 2 ]

  9. Permanganate - Wikipedia

    en.wikipedia.org/wiki/Permanganate

    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 ...
