Final answer:
To find the cell potential for a voltaic cell with Cu²⁺|Cu and Fe²⁺|Fe electrodes, subtract the standard electrode potential of the anode from that of the cathode. The given E° for Cu is +0.337V, whereas the E° for Fe needs to be looked up.
Step-by-step explanation:
The question asks about the cell potential for a standard voltaic cell comprised of a Cu²⁺|Cu electrode and a Fe²⁺|Fe electrode. To calculate the standard cell potential (E°cell), we use the standard electrode potentials (E°) for each half-cell reaction given in standard reduction potential tables. We take the standard reduction potential for the copper ion reduction (Cu²⁺ + 2e⁻ → Cu(s), E° = +0.337 V) and the standard reduction potential for the iron ion reduction (Fe²⁺ + 2e⁻ → Fe(s), E° values should be looked up in a standard reduction potentials table). The cell potential is calculated by subtracting the anode's potential (the lower value) from the cathode's potential (the higher value). If the E° for iron is not given, please consult a standard reduction potential table to find that value before completing the calculation.
