Homework Help: Redox reaction ferrocyanide

  1. Feb 1, 2008 #1
    Help me please to finish this reaction of the ferrocyanide reduction:
    K3Fe(CN)6 + Na2S2O3 + H2O=...?

    the electron transfer reaction inthis case is
    2Fe(CN)3-6 + 2S2O3 = 2Fe(CN)4-6 + S4O2-6.

    Wondering what are the final products of the upper reaction.

    ferrocyanide reaction

    Thanks for reply.
    I think that I have already written the final products of this reaction:
    2Fe(CN)4-6 and S4O2-6 - ionic parts, (K4[Fe(CN)4] and sodium thiosilfate). Hope it's right...
