In Castner Kellner cell:
Correct answer: D. NaOH+H2 are produced at cathod and Cl2 is produced at anode
- A. NaOH+ H2 are produced at cathode
- B. Cl2 is produced at anode
- C. NaOH+H2 are produced at anode
- D. NaOH+H2 are produced at cathod and Cl2 is produced at anode
- E. Cl2 is produced at cathode
Explanation
In the Castner-Kellner cell, option (d) is correct: NaOH + H2 is produced at the cathode, and Cl2 is produced at the anode. The Castner-Kellner cell is an electrolytic cell used for the production of sodium hydroxide (NaOH) and chlorine gas (Cl2) through the electrolysis of brine (sodium chloride solution). So option D is the correct answer.

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.
