Why does polarization not occur in dry cell?
Why does polarization not occur in dry cell? 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. What is local action […]
