Question
Distinguish between Leclanche cell and Lead storage battery.
✓
Answer
Leclanche Cell
1. It is a primary cell
2. It is a non-rechargeable cell
3. Anode : Zinc container
Cathode : Graphite rod in contact with $MnO _2$
4. Electrolytes: Ammonium chloride and zinc chloride in water
5. Emf of the cell $=1.5 V$
Lead storage battery
1. It is a secondary cell
2. It is rechargeable cell
3. Anode: Spongy lead
Cathode : Lead plate bearing $PbO _2$
4. Electrolytes: $38 \%$ by mass of $H _2 SO _4$ with density $1.2 g / ml$
5. emf of the cell $2 V$.
