Question:medium

Identify the gas produced due to reduction of $NH_{4}^{+}$ ions at cathode during working of dry cell.

Show Hint

Logic Tip: The ammonia ($NH_3$) produced in this reaction does not evolve as a gas. Instead, it complexes with the $Zn^{2+}$ ions produced at the anode to form the complex ion $[Zn(NH_3)_4]^{2+}$, which helps maintain a steady concentration of ions in the paste.
