The anode in a dry cell consists of
(1) Copper
(2) Zinc
(3) Cadmium
(4) Graphite
Answer: (2) A “dry-cell” battery is essentially comprised of a metal electrode or graphite rod (elemental carbon) surrounded by a moist electrolyte paste enclosed in a metal cylinder. The cathode is composed of a form of elemental carbon called graphite, which serves as solid support for the reduction half-reaction. A thin zinc cylinder serves as the anode, and it undergoes oxidation.
