Assertion (A) \(\mathrm{P}_4 \mathrm{O}_{10}\) cannot be used to remove moisture from ammonia gas. Reason (R) \(\mathrm{P}_4 \mathrm{O}_{10}\) reacts with \(\mathrm{NH}_3\) gas. The correct answer is
- A Both A and (R) are correct and (R) is the correct explanation of (A)
- B Both A and (R) are correct and (R) is not the correct explanation of (A)
- C (A) is correct but (R) is not correct
- D (A) is not correct but (R) is correct
Answer & Solution
Correct Answer
(A) Both A and (R) are correct and (R) is the correct explanation of (A)
Step-by-step Solution
Detailed explanation
\(\mathrm{P}_4 \mathrm{O}_{10}\) can not be used to remove moisture from ammonia gas because it reacts with \(\mathrm{NH}_3\). \[ 12 \mathrm{NH}_3+\mathrm{P}_4 \mathrm{O}_{10}+6 \mathrm{H}_2 \mathrm{O} \rightarrow 4\left(\mathrm{NH}_4\right)_3 \mathrm{PO}_4 \] Hence, Assertion…
