Mohr's salt $\xrightarrow{NaOH \, \text{solution}} NH_{3} \uparrow (g)$

(B) Mohr's salt is $(NH_{4})_{2}SO_{4} \cdot FeSO_{4} \cdot 6H_{2}O$. When Mohr's salt reacts with $NaOH$ solution,the ammonium ion $(NH_{4}^{+})$ reacts with the hydroxide ion $(OH^{-})$ to release ammonia gas $(NH_{3} \uparrow)$. The reaction is: $(NH_{4})_{2}SO_{4} + 2NaOH \to Na_{2}SO_{4} + 2H_{2}O + 2NH_{3} \uparrow$.
