Answer:
Manganese oxide prevents polarisation in dry cells. - Polarization is a defect that occurs in simple electric cells due to the accumulation of hydrogen gas around the positive electrode. ... - MnO2 reacts with H2 and forms water as byproduct, so depolarization doesn't occur

Manganese oxide prevents polarisation in dry cells.
Explanation:
- A dry-cell battery stores energy in an immobilized electrolyte paste, which minimizes the need for water.
- Polarization is a property applying to transverse waves that specifies the geometrical orientation of the oscillations.
- In a transverse wave, the direction of the oscillation is perpendicular to the direction of motion of the wave.
- 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.
