Q. In a dry cell (battery), which of the following are used as electrolytes?
Answer: Ammonium chloride and Zinc chloride
Notes: In a dry cell (Leclanchè cell), the electrolyte is a paste mixture containing ammonium chloride (NH₄Cl) and zinc chloride (ZnCl₂). Ammonium chloride serves as the primary electrolyte allowing ion movement between electrodes, while zinc chloride improves conductivity and the cell's performance. The zinc container acts as the anode, and a carbon rod serves as the cathode. This combination is standard in commercial dry cells used in portable devices. Other options list incorrect electrolyte pairs not used in dry cells.
