Which of the following chemicals may be used to identify three unlabelled beakers containing conc.NaOH, conc.\(\mathrm{H}_{2}\mathrm{SO}_{4}\) and water?
- A \(\mathrm{NH}_{4} \mathrm{NO}_{3}\)
- B \(\mathrm{NaCl}\)
- C \(\left(\mathrm{NH}_{4}\right)_{2} \mathrm{CO}_{3}\)
- D HCOONa
Answer & Solution
Correct Answer
(C) \(\left(\mathrm{NH}_{4}\right)_{2} \mathrm{CO}_{3}\)
Step-by-step Solution
Detailed explanation
\(\mathrm{NH}_{4} \mathrm{NO}_{3}\) will evolve \(\mathrm{NH}_{3}\) pungent smelling gas with \(\mathrm{NaOH}\). - \(\mathrm{NO}_{2}\) brown gas with \(\operatorname{con} . \mathrm{H}_{2} \mathrm{SO}_{4}\) - No reaction with water Thus, \(\mathrm{NH}_{4} \mathrm{NO}_{3}\) can be…
