Question

A zinc-copper cell can be written as
Options
A Zn²⁺(aq)/Zn(s)//Cu(s)/Cu²⁺(aq)
B Zn(s)/Zn²⁺(aq)/Cu(aq)/Cu(s)
C Zn(s)/Zn²⁺(aq)//Cu²⁺(aq)/Cu(s)
Correct Answer
D Zn²⁺(aq)/Zn(s)/Cu(s)/Cu²⁺(aq)
Correct Answer

Option C is the correct answer.

Detailed Explanation

Cell notation convention: anode | oxidized species || reduced species | cathode. Zinc is oxidized (anode), copper is reduced (cathode). The double line represents the salt bridge. So: Zn(s) | Zn²⁺(aq) || Cu²⁺(aq) | Cu(s).

Hint

Anode (oxidation) is written on the left, cathode (reduction) on the right. The salt bridge is represented by //.
