Redox reactions and oxidation

  • #1
Hi ppl. I'm asked a question: Iron filings are added to a solution containing the ions Cu2+, Fe2+, Fe3+, H30+ and Zn2+. Deduce what reactions occur from the standard electrode potentials. Is this simply asking me which will change Fe2+ to Fe3+ and vice-versa by reduction or oxidation do you think? Thx a lot, Joe

I am sure you were given standard electrode potentials, from there it wouldn't be hard to deduce which would undergo oxidation versus the one undergoing reduction.

Interestingly enough, I still have this url on the clipboard

Cu2+ will reduce, Fe2+ does nothing, Fe3+ will reduce, H+ will reduce, Zn2+ does nothing, the iron filings will oxidize whenever possible.
