Here's the solution for the Zinc-copper cell: i) The standard electrode potential of Zinc (-0.76 V) is more negative than that of Copper (+0.34 V). This means Zinc will be oxidized (anode) and Copper ions will be reduced (cathode). W is the electrode where oxidation occurs. The identity of W is the Zinc electrode (Zn). ii) X is the electrolyte in the half-cell where reduction occurs. Copper ions are reduced to copper metal. The identity of X is a Copper(II) salt solution (e.g., CuSO_4(aq) or Cu(NO_3)_2(aq)). iii) The equation for the overall cell reaction: Anode (oxidation): Zn(s) Zn^2+(aq) + 2e^- Cathode (reduction): Cu^2+(aq) + 2e^- Cu(s) Overall cell reaction: Zn(s) + Cu^2+(aq) Zn^2+(aq) + Cu(s) iv) The reading on the voltmeter is the standard cell potential (E^_cell). E^_cell = E^_cathode - E^_anode E^_cell = E^_Cu^2+/Cu - E^_Zn^2+/Zn E^_cell = (+0.34 V) - (-0.76 V) E^_cell = 0.34 V + 0.76 V E^_cell = 1.10 V 3 done, 2 left today. You're making progress.
