  2. Permanganate - Wikipedia

    en.wikipedia.org/wiki/Permanganate

    A permanganate can oxidize an amine to a nitro compound, [7] [8] a secondary alcohol to a ketone, [9] a primary alcohol or 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 ...

  3. 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 ...

  4. Soil acidification - Wikipedia

    en.wikipedia.org/wiki/Soil_acidification

    Impacts of acidic water and Soil acidification on plants could be minor or in most cases major. In minor cases which do not result in fatality of plant life include; less-sensitive plants to acidic conditions and or less potent acid rain. Also in minor cases the plant will eventually die due to the acidic water lowering the plants natural pH.

  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. 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: 14 KMnO 4 (s) + 4 C 3 H 5 (OH) 3 (l) → 7 K 2 CO 3 (s) + 7 Mn 2 O 3 (s) + 5 CO 2 ...

  7. Soil pH - Wikipedia

    en.wikipedia.org/wiki/Soil_pH

    Rainfall: Average rainfall has a pH of 5.6 and is moderately acidic due to dissolved atmospheric carbon dioxide (CO 2) that combines with water to form carbonic acid (H 2 CO 3). When this water flows through the soil it results in the leaching of basic cations as bicarbonates; this increases the percentage of Al 3+ and H + relative to other ...

  8. Soil formation - Wikipedia

    en.wikipedia.org/wiki/Soil_formation

    Additionally, some bacteria can fix atmospheric nitrogen, and some fungi are efficient at extracting deep soil phosphorus and increasing soil carbon levels in the form of glomalin. [69] Plants hold soil against erosion, and accumulated plant material build soil humus levels. Plant root exudation supports microbial activity.

  9. Alkali soil - Wikipedia

    en.wikipedia.org/wiki/Alkali_soil

    Water with excess H 3 O + ions is called acid (pH < 7), and water with excess OH – ions is called alkaline or rather basic (pH > 7). Soil moisture with pH < 4 is called very acid and with pH > 10 very alkaline (basic). H 2 CO 3 (carbonic acid) is unstable and produces H 2 O (water) and CO 2 (carbon dioxide gas, escaping into the
