Which of the following paste is used in dry cell as an electrolyte?
Show Hint
In the Leclanche dry cell, the electrolyte is a moist paste of ammonium chloride and zinc chloride.
Updated On: Nov 12, 2026
- Paste of ammonium chloride (\(\text{NH}_{4}\text{Cl}\)) and zinc chloride (\(\text{ZnCl}_{2}\))
- Paste of manganese dioxide (\(\text{MnO}_{2}\)) and carbon black
- Paste of potassium hydroxide (KOH) and zinc oxide (ZnO)
- Paste of sodium hydroxide ( NaOH ) and zinc chloride (\(\text{ZnCl}_{2}\))

The Correct Option is A
Solution and Explanation
Step 1: Understanding the Concept
In the dry (Leclanche) cell, the zinc container is the anode and a graphite rod is the cathode.
Step 2: Parts of the cell
The graphite rod is surrounded by a mixture of \(\text{MnO}_2\) and carbon, which acts as the depolariser. Between the electrodes lies a moist paste of \(\text{NH}_4\text{Cl}\) and \(\text{ZnCl}_2\).
Step 3: Result
This paste carries the ions, so it is the electrolyte. KOH paste is used in alkaline cells, not in the ordinary dry cell.
Final Answer:
The electrolyte is the paste of ammonium chloride and zinc chloride, which is option (A). \[ \boxed{\text{(A) }\text{Paste of ammonium chloride and zinc chloride}} \]
