Question

The polarisation takes place in a simple voltaic cell on account of the deposition of

• A. atomic hydrogen on zinc plate
• B. atomic hydrogen on copper
• C. molecular hydrogen on zinc plate
• D. molecular hydrogen on copper plate

Answer 1

The correct option is D

molecular hydrogen on copper plate

1. It is a defect of voltaic cell in which molecular hydrogen on copper plate
2. The process due to which the electric current in a simple voltaic cell dies on account of the deposition of molecular hydrogen on the copper plate is called polarization

Hence, option (D) is correct.
