    Potassium permanganate is an inorganic compound with the chemical formula KMnO 4.It is a purplish-black crystalline salt, which dissolves in water as K + and MnO − 4 ions to give an intensely pink to purple solution.

  6. Molecular diffusion - Wikipedia

    en.wikipedia.org/wiki/Molecular_diffusion

    If no bulk flow occurs in an element of length dx, the rates of diffusion of two ideal gases (of similar molar volume) A and B must be equal and opposite, that is =. The partial pressure of A changes by dP A over the distance dx. Similarly, the partial pressure of B changes dP B. As there is no difference in total pressure across the element ...

  8. Alcohol oxidation - Wikipedia

    en.wikipedia.org/wiki/Alcohol_oxidation

    Through a variety of mechanisms, the removal of a hydride equivalent converts a primary or secondary alcohol to an aldehyde or ketone, respectively. The oxidation of primary alcohols to carboxylic acids normally proceeds via the corresponding aldehyde, which is transformed via an aldehyde hydrate ( gem -diol, R-CH(OH) 2 ) by reaction with water.
