Homework Help: OF2 + H2O -> O2 + 2HF What's being oxidized and what's being reduced?

    1. The problem statement, all variables and given/known data
    Hi all,

    I'm going back through some previous exam papers, and one of the questions is:

    Use oxidation numbers to identify which substances are oxidized and which are reduced:
    OF2 + H2O -> O2 + 2HF

    I know the oxygen in OF2 is a special case, so to me it looks like OF2 is being oxidized, but it I don't know what's happening the H2O...

    Can anyone shed any light on this please?

    Thanks a lot!
