  2. Potassium permanganate - Wikipedia

    en.wikipedia.org/wiki/Potassium_permanganate

    The reagent is an alkaline solution of potassium permanganate. Reaction with double or triple bonds (R 2 C=CR 2 or R−C≡C−R) causes the color to fade from purplish-pink to brown. Aldehydes and formic acid (and formates) also give a positive test. [43] The test is antiquated. Baeyer's reagent reaction

  3. Glycerol and potassium permanganate - Wikipedia

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

    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]

  4. Potassium manganate - Wikipedia

    en.wikipedia.org/wiki/Potassium_manganate

    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.

  5. Permanganate - Wikipedia

    en.wikipedia.org/wiki/Permanganate

    When used to oxidize organic compounds, the exact chemical reaction depends on the organic reactant present. 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 −). [6] 8 MnO − 4 + 3 C 2 H 3 Cl 3 → 6 CO 2 + 8 MnO 2 ...

  6. Rubidium permanganate - Wikipedia

    en.wikipedia.org/wiki/Rubidium_permanganate

    Similar to potassium permanganate, the two-step decomposition of rubidium permanganate leads to the formation of rubidium manganate intermediates. It breaks down into manganese dioxide, rubidium oxide and oxygen. [4] The decomposition temperature is between 200 and 300 °C. [7] Drift-away oxygen caused an 8% mass loss in the product. [7]

  7. Chemistry of ascorbic acid - Wikipedia

    en.wikipedia.org/wiki/Chemistry_of_ascorbic_acid

    Historically, industrial preparation via the Reichstein process used potassium permanganate as the bleaching solution. Acid-catalyzed hydrolysis of this product performs the dual function of removing the two acetal groups and ring-closing lactonization. This step yields ascorbic acid. Each of the five steps has a yield larger than 90%. [37]

  8. Potassium ferrocyanide - Wikipedia

    en.wikipedia.org/wiki/Potassium_ferrocyanide

    Molar mass: 368.35 g/mol (anhydrous) ... is used to determine the concentration of potassium permanganate, a compound often used in titrations based on redox reactions.

  9. Potassium dichromate - Wikipedia

    en.wikipedia.org/wiki/Potassium_dichromate

    Potassium dichromate is an oxidising agent in organic chemistry, and is milder than potassium permanganate. It is used to oxidize alcohols. It converts primary alcohols into aldehydes and, under more forcing conditions, into carboxylic acids. In contrast, potassium permanganate tends to give carboxylic acids as the sole products.
