A solution of \(\mathrm{NaNO}_{3}\), when treated with a mixture of \(\mathrm{Zn}\) dust and ' \(\mathrm{A}\) ' yields ammonia. ' \(\mathrm{A}\) ' can be
- A caustic soda
- B dilute sulphuric acid
- C concentrated sulphuric acid
- D sodium carbonate
Answer & Solution
Correct Answer
(A) caustic soda
Step-by-step Solution
Detailed explanation
\(\mathrm{NaNO}_{3}+4 \mathrm{Zn}+\frac{7 \mathrm{NaOH}}{(\mathrm{A})} \rightarrow 4 \mathrm{Na}_{2} \mathrm{ZnO}_{2}+\mathrm{NH}_{3}+2 \mathrm{H}_{2} \mathrm{O}\) A is caustic soda
