Question

Which substance is used as depolarizer in Leclanche cell?

Answer 1

The Leclanché cell is a battery invented and patented by the French scientist Georges Leclanché in 1866. The battery contained a conducting solution (electrolyte) of ammonium chloride, a cathode (positive terminal) of carbon, a depolarizer of manganese dioxide, and an anode (negative terminal) of zinc. The chemistry of this cell was later successfully adapted to manufacture a dry cell.
