Homework Help: Galvanic cell

  1. Jul 31, 2008 #1
    iwe had an expirament that goes like this
    we made a galvanic cell with half cell zinc and its solution (Zn(NO3)2) and the other half cell was with iron and its solution (Fe(NO3)3) (the Fe solution with ions Fe+3) (both same concentration!) the potential i measured was 0.287V
    now i just dont understand how can this be
    because the standard potential of Fe+3 + e -> Fe+2 is 0.77V and for Zink it is -0.76V thus we should get in the experiment that the measured potential is 1.53V i just cant understand my result
    help please

    You won't get different answer here than the one I have posted on chemical forums.
