Question

The correct cell notation for a Daniell cell (zinc-copper) is:
Options
A Zn(s) | Zn²⁺(aq) || Cu²⁺(aq) | Cu(s)
Correct Answer
B Cu(s) | Cu²⁺(aq) || Zn²⁺(aq) | Zn(s)
C Zn²⁺(aq) | Zn(s) || Cu(s) | Cu²⁺(aq)
D Cu²⁺(aq) | Cu(s) || Zn(s) | Zn²⁺(aq)
Correct Answer

Option A is the correct answer.

Detailed Explanation

Zinc is more easily oxidized, so it is the anode (left side). Copper is the cathode (right side). The notation is: anode | oxidized species || reduced species | cathode.

Hint

Anode (oxidation) is on the left, cathode (reduction) on the right.
