For a Voltaic Cell containing Zn and Copper electrodes, the cell potential at standard conditions is?

Explanation

For a Voltaic Cell containing Zn and Copper electrodes, the cell potential at standard conditions is always 1.1 V. The cell potential of a voltaic cell containing Zn and Cu electrodes at standard conditions is determined by the standard reduction potentials of the half-reactions involved. The half-reactions for the Zn/Cu cell are Zn(s) → Zn2+(aq) + 2 e− E°red = -0.76 V Cu2+(aq) + 2 e− → Cu(s) E°red = +0.34 V The cell potential (E°cell) is calculated by subtracting the standard reduction potential of the anode from that of the cathode: E°cell = E°reduction (cathode) - E°reduction (anode) E°cell = +0.34 V - (-0.76 V) E°cell = +1.10 V Therefore, the cell potential of a Zn/Cu voltaic cell at standard conditions is +1.10 V.
