  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. Potassium permanganate (medical use) - Wikipedia

    en.wikipedia.org/wiki/Potassium_permanganate...

    Potassium permanganate is an oxidizing agent. [5] The British National Formulary recommends that each 100 mg be dissolved in a liter of water before use. [3] Potassium permanganate was first made in the 1600s and came into common medical use at least as early as the 1800s. [6] It is on the World Health Organization's List of Essential Medicines ...

  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 .

  5. Permanganic acid - Wikipedia

    en.wikipedia.org/wiki/Permanganic_acid

    Potassium permanganate, KMnO 4, is a widely used, versatile and powerful oxidising agent. Permanganic acid solutions are unstable, and gradually decompose into manganese dioxide, oxygen, and water, with initially formed manganese dioxide catalyzing further decomposition. [6] Decomposition is accelerated by heat, light, and acids.

  6. Ionic strength - Wikipedia

    en.wikipedia.org/wiki/Ionic_strength

    The ionic strength of a solution is a measure of the concentration of ions in that solution. Ionic compounds, when dissolved in water, dissociate into ions. The total electrolyte concentration in solution will affect important properties such as the dissociation constant or the solubility of different salts. One of the main characteristics of a ...

    en.wikipedia.org/wiki/Permanganometry

    Depending on the conditions in which the titration is performed, the manganese is reduced from an oxidation of +7 to +2, +4, or +6. In most cases, permanganometry is performed in a very acidic solution in which the following electrochemical reaction occurs: [3]
