The circuit shown in diagram was set up
Correct answer: D. D
- A. A
- B. B
- C. C
- D. D
Explanation
The given figure shows (Cu + Zn) electrode connected with SHE. If Zn electrode act as anode, then Hydrogen gas will evolve at cathode. If Cu electrdoe act as cathode, then Hydrogen will evolve at anode. Since in option D Zn is deposited at anode and hydrogen is evolved at cathode, so it is correct.

About Electrochemistry
Electrochemistry describes electron transfer through oxidation and reduction, identifies oxidizing and reducing agents, and applies oxidation numbers to balance redox equations. It also covers electrode potential and the standard hydrogen electrode, which provides the reference for comparing the reduction tendencies of other electrodes.
