单词 disproportionation
释义
disproportionation

Chemistry
  • A type of chemical reaction in which the same compound is simultaneously reduced and oxidized. For example, copper(I) chloride disproportionates thus:

    2CuClCu+CuCl2

    The reaction involves oxidation of one molecule

    CuICuII+e

    and reduction of the other

    CuI+eCu

    The reaction of halogens with hydroxide ions is another example of a disproportionation reaction, for example

    Cl2(g)+2OH-(aq)Cl-(aq)+ClO-(aq)+H2O(l)

    The reverse process is comproportionation.
