Question 5e) 2009 VCAA Exam

Hi guys,

I was wondering what the answer to that question is? I read the answer for it on the VCAA report but I didn't really understand why Iron cannot be used as an electrode here!!

Thanks :)

Fe oxidizes during discharge in preference to the V2+

A census taker once tried to test me. I ate his liver with some fava beans and a nice Chianti.

Thanks for the concise answer Dr Lecter :) for some reason I thought that using an iron electrode would mean that V2+/V3+ disappeared
