Question

In a dry cell _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ containing a moist paste of plaster of Paris, NH4Cl and ZnCl act as
A. Copper vessel, Cathode
B. Zinc vessel, Cathode
C. Zinc vessel, Anode
D. Copper vessel, Anode

Answer 1

Hint: Ammonium chloride and the zinc chloride are used in the form of an electrolyte of the dry cell that is the battery.

Complete step by step solution:
Ammonium chloride is mixed with Plaster of Paris to form a paste, with a small amount of zinc chloride added to increase the life of the battery.
The paste of the ammonium chloride is allowing the flow of the electric current.
Zinc chloride paste allows a dry cell to conduct the electricity and to provide the electrical power to the different substances.
 Zinc chloride paste, used in between the space of the anode and the cathode electrodes in a dry cell along with the moist paste of the ammonium chloride where zinc chloride as an electrolyte.
A dry cell is a type of the battery which we used as movable electrical devices. A standard dry cell involves a zinc anode, in the form of the cylindrical pot, with a carbon cathode in the form of a central rod.
 So, the electrolyte is ammonium chloride in the form of a paste next to the zinc anode.

So, the correct answer is “Option C”.

Note: Dry cells contain the zinc container which works as a negative electrode. The moist paste is made up of a mixture of the Plaster of Paris, Ammonium chloride and Zinc chloride. The moist paste is known as Sal Ammoniac Paste. The carbon rod forms the positive electrode. The powdered carbon reduces the internal resistance of the cell.
