Consider an electrochemical cell as shown, with Zn in ZnClz(aq) and Cu in Cu(NO3)2(aq), and a salt bridge containing KNO3(aq). The overall chemical reaction is Zn(s) + Cu? (aq) → Zn²^(aq) + Cu(s). Which statement is correct? One mole of electrons is transferred in this reaction. Electrons travel from the Zn to the Cu. Zinc is reduced at the cathode. This is an example of a concentration cell. O Copper is oxidized at the anode.
