Oxidation and reduction Disproportionation

  1. Mar 13, 2005 #1
    We call reactions in which one species experiences both oxidation and reduction Disproportionation - but why do we chose this particular name?

    Thanks. :smile:

    The adjective disproportionate means "not proportioned, unsymmertrical, unsuitable to something in bulk, etc". In a redox reaction, if the two species undergoing redox are of the same kind (oxidation number), then we call this reaction as "disproportionation". There is an obvious unsymmetrical nature in this, if you study the reactions. This reaction is characteristic for species which are in a medium oxidation state; if there are oxidation states available below and above this state, disproportionation can be possible.
