Which of the following is used to avoid leakage of electrolyte in dry cell?

Options

APaste of MnO ₂
BPaste of NH ₄ Cl
CStarch
DPaste of ZnCl ₂

Correct answer

C. Starch

Step-by-step solution

Cathode is an inert graphite rod in the center of the cell immersed in an electrolyte paste. Electrolyte is moist paste of ammonium chloride and zinc chloride. Starch is added to the paste make it thick so that it cannot be leaked out.
