Q1. In a dry cell (battery), which of the following are used as electrolytes?
Explanation
Ammonium chloride (NH₄Cl) is a primary component of the electrolyte paste used in dry cells. Zinc chloride (ZnCl₂) serves as the negative electrolyte, and it is often mixed with ammonium chloride in a paste to form the electrolyte for the dry cell. These components, along with a zinc anode and a carbon cathode, are commonly used in the construction of dry cells, which power small devices such as flashlights and radios.
