Web15.7.2 Potential difference from combining half cells, Zn and Cu, Zn and Pb. If Zn E 0 = -0.76 V set up cells to measure the E 0 values of copper (copper in copper (II) sulfate solution) and lead (lead in lead (II) nitrate solution). 15.7.3 Differences in potential on an iron nail. WebAnd look-- there's someone to take those electrons from. And so what you get is a redox reaction. And we'll look at the half reactions in a second. You get a redox reaction where the copper takes electrons from the zinc. So it becomes neutral solid copper. And the zinc loses those electrons to the copper. And so those become zinc cations.
