Zn–Cu Cell — Electrochemistry Chemistry Question

💡 Solution & Explanation

The standard cell potential is the difference between the reduction potentials of the cathode and anode: $E^\circ_{cell} = E^\circ_{cathode} - E^\circ_{anode}$. Using the new values: $E^\circ_{cell} = (+1.34 \text{ V}) - (+0.24 \text{ V}) = +1.10$ V. The arbitrary shift in the reference scale cancels out, leaving the measurable cell EMF unchanged.
