In a normal dry cell, the electrolyte is

The correct answer is Ammonium chloride (option C). In a normal dry cell, such as the standard alkaline battery commonly used in household devices, the electrolyte consists of a paste composed mainly of ammonium chloride (NH4Cl) mixed with zinc chloride (ZnCl2). This paste serves several critical functions: it provides ionic conductivity necessary for the electrochemical reactions to occur, helps maintain the cell’s internal chemistry, and contributes to the overall performance and lifespan of the battery. The electrolyte interacts with the anode (typically zinc) and cathode (usually manganese dioxide), facilitating the flow of ions and electrons essential for generating electrical power. Understanding the composition and role of the electrolyte in dry cells is fundamental for optimizing battery performance and ensuring reliable operation in various applications, from portable electronics to automotive and industrial uses.
