Homework Help: Oxidation states of manganese and pH

  1. May 31, 2010 #1
    Hi

    I am interested in the change in the stability of the oxidation states of manganese with pH

    Mn is a stronger oxidising agent in acid than in base which would lead you to believe that the higher oxidation states of Mn are more stable in alkaline conditions.

    Does anyone have a reason why? I couldnt find one

    Thanks

    There is a brown precipitate forming in solutions of permanganate. Have you tried to write reaction equation for the decomposition reaction? What are products of the decomposition?
