The common acid dry cell battery typically contains an inner casing made of _____ metal, which functions as the anode.

Concept Introduction:

A dry cell battery is a form of electrical battery. It consists of anode and cathode to which oxidation and reduction reaction takes place. Redox reactions are defined as the oxidation-reduction reactions in which the oxidation states of atoms are changed by the transfer of electrons between two species.

Explanation

A dry cell battery is a form of electrical battery. The dry cell battery consists of inner case made up of zinc. It acts as the anode and a carbon rod that acts as the cathode. In a dry cell battery, the carbon rod is in contact with a moist paste of solid MnO2 and solid NH4Cl. The half cell reactions that occur in a dry cell are shown below.

Anode: ZnZn2++2e(oxid
