Ammonium chloride is used as dry cell in electrolyte. Can u explain this clearly?


Ammonium chloride is a strong electrolyte. In dry cell, the electrolyte ammonium chloride forms ammonium ion and chloride ions. The chloride ions move towards zinc electrode where they oxidise Zinc to zinc chloride. The ammonium ions move towards the carbon electrode where they reduce manganese dioxide to Mn2O3 with the formation of ammonia and water. The ammonia thus formed is not liberated as gas but it combines with zinc ions and chloride ions to form a complex salt.
It used in dry cell in jelly form as an electrolyte in it so that it does not leak out..
