Rust and electrode
« on: February 21, 2008, 12:18:02 AM »
Does a rusted electrode, let's say iron, have an effect on a voltaic cell?

rust is an Very bad conductor (isolator). So yes, it will lower the potential of the cell if the electrode is completely covered as energy is needed to overcome the conductivity barrier.
