In normal chemical cells, the electrodes are two different metals so that the more reactive one gives off electrons and create a flow of electrons and hence electricity. [the electrolyte is say NaOH aq or whatever]
Just wondering - is it possible to have a chemical cell consisting of:
a) Copper / graphite electrodes
b) Zinc / graphite electrodes
The metal in the above - can they give off electrons and becomes ion and create a flow of electrons / electricity?
thanks
