Now, suppose we have an electrochemical cell able to take cell that's composed of the following redox reaction. So it has an oxidation reaction and a reduction reaction. Our zinc solid is oxidized into zinc ion, while our copper ion is reduced to copper solid. So, this guy releases two electrons, while this guy takes those two electrons, gains two electrons forming our copper solid. Now, these electrons in the end, end up crossing out. Now, our cell voltage is 1.1 volt.
