Calculate the emf of the cell Zn | Zn2+(1 M) || Cu2+(1 M) | Cu, given E° for Zn2+/Zn = −0.76 V and for Cu2+/Cu = +0.34 V.
Original Khojo Papers practice question — not from a past board paper.
Answer
1.10 V
No citable source has been recorded for this record. Treat it as practice material, not as fact.
Explanation
The cell emf is the cathode potential minus the anode potential, 0.34 − (−0.76) = 1.10 V.
