Question

polarization doesnt occur in dry cell. why

Answer 1

sorry I don't no the answer

Answer 2

Hey dear,

● Answer -
Manganese oxide prevents polarisation in dry cells.

● Polarization -
- Polarization is a defect that occurs in simple electric cells due to the accumulation of hydrogen gas around the positive electrode.
- Deepolarizer like manganese oxide is added in dry cell.
- MnO2 reacts with H2 and forms water as byproduct, so depolarization doesn't occur.


Hope this helped you...
