problem of a redox reaction
« on: March 24, 2011, 07:43:55 AM »
how many electrons are transfered from oxidant to reductant and reducatnt to oxidant in the reaction.


Al + Fe2O3  :rarrow: Fe + Al2O3

Balance this reaction. May be then all will be clear.

or maybe even easier to do: make 2 separate half reactions --one for Fe, one for Al-- assuming O2- to be the source/product of O for balancing (it isn't but the O formed will cancel out the O consumed, making this the easiest balancing tool), then look at the electrons consumed/formed in each half-reaction compared to the number of metal atoms used in each reaction
