  2. 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 ...

  3. Permanganate - Wikipedia

    en.wikipedia.org/wiki/Permanganate

    A permanganate can oxidize an amine to a nitro compound, [7] [8] an alcohol to a ketone, [9] an aldehyde to a carboxylic acid, [10] [11] a terminal alkene to a carboxylic acid, [12] oxalic acid to carbon dioxide, [13] and an alkene to a diol. [14] This list is not exhaustive. In alkene oxidations one intermediate is a cyclic Mn(V) species: [15]

  4. Glycerol and potassium permanganate - Wikipedia

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

    Potassium permanganate (KMnO 4) is a dark violet colored powder. Its reaction with glycerol (commonly known as glycerin or glycerine) (C 3 H 5 (OH) 3) is highly exothermic, resulting rapidly in a flame, along with the formation of carbon dioxide and water vapour:

  5. Permanganic acid - Wikipedia

    en.wikipedia.org/wiki/Permanganic_acid

    As a strong acid, HMnO 4 is deprotonated to form the intensely purple coloured permanganates. 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 ...

  6. Manganese dioxide - Wikipedia

    en.wikipedia.org/wiki/Manganese_dioxide

    To complete the process, a suspension of this material in sulfuric acid is treated with sodium chlorate. Chloric acid, which forms in situ, converts any Mn(III) and Mn(II) oxides to the dioxide, releasing chlorine as a by-product. [8] Lastly, the action of potassium permanganate over manganese sulfate crystals produces the desired oxide. [9] 2 KMnO

  7. Soil acidification - Wikipedia

    en.wikipedia.org/wiki/Soil_acidification

    Basic cations like calcium are leached from the soil as acidic rainfall flows, which allows aluminum and proton levels to increase. [ 3 ] [ 4 ] Nitric and sulfuric acids in acid rain and snow can have different effects on the acidification of forest soils, particularly seasonally in regions where a snow pack may accumulate during the winter.

  9. Greensand - Wikipedia

    en.wikipedia.org/wiki/Greensand

    Greensand glauconite is used as a water softener for its chemical-exchange properties. Greensand coated with manganese oxide (called manganese greensand) is used in well water treatment systems to remove dissolved (reduced) iron and manganese with the addition of an oxidant, usually potassium permanganate, under controlled pH conditions.
