  2. 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.

  3. Permanganate - Wikipedia

    en.wikipedia.org/wiki/Permanganate

    A permanganate (/ p ər ˈ m æ ŋ ɡ ə n eɪ t, p ɜːr-/) [1] is a chemical compound with the manganate(VII) ion, MnO − 4, the conjugate base of permanganic acid. Because the manganese atom has a +7 oxidation state, the permanganate(VII) ion is a strong oxidising agent. The ion is a transition metal ion with a tetrahedral structure. [2]

  4. Potassium permanganate - Wikipedia

    en.wikipedia.org/wiki/Potassium_permanganate

    The value determined is known as the permanganate value. In analytical chemistry, a standardized aqueous solution of KMnO 4 is sometimes used as an oxidizing titrant for redox titrations (permanganometry). As potassium permanganate is titrated, the solution becomes a light shade of purple, which darkens as excess of the titrant is added to the ...

    en.wikipedia.org/wiki/Manganate

    4, also known as manganate(VI) because it contains manganese in the +6 oxidation state. [1] Manganates are the only known manganese(VI) compounds. [2] Other manganates include hypomanganate or manganate(V), MnO 3− 4, permanganate or manganate(VII), MnO − 4, and the dimanganate or dimanganate(III) Mn 2 O 6− 6. A manganate(IV) anion MnO 4−

  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]

    As long as a non-native plant is not invasive, some can also help pollinators by providing nectar and pollen throughout the season, often filling in the gaps for the native plants.

  8. Caesium permanganate - Wikipedia

    en.wikipedia.org/wiki/Caesium_permanganate

    Similar to potassium permanganate, the two-step decomposition of caesium permanganate leads to the formation of caesium manganate intermediates. It breaks down into manganese dioxide, caesium oxide and oxygen. [5] The decomposition temperature is between 200 and 300 °C. [6] Drift-away oxygen caused an 8% mass loss in the product. [6]

  9. Manganese - Wikipedia

    en.wikipedia.org/wiki/Manganese

    Aside from various permanganate salts, Mn(VII) is represented by the unstable, volatile derivative Mn 2 O 7. Oxyhalides (MnO 3 F and MnO 3 Cl) are powerful oxidizing agents. [11] The most prominent example of Mn in the +6 oxidation state is the green anion manganate, [MnO 4] 2−. Manganate salts are intermediates in the extraction of manganese ...
