Question

P 4 O 10 is not used to dry NH 3 gas because (A) P 4 O 10 is not a drying agent (B) P 4 O 10 reacts with moisture in NH 3 (C) P 4 O 10 is basic and NH 3 is acidic (D) none of these.

P 4 O 10 is acidic and NH 3 is basic, so they react with each other in presence of moisture giving ammonium phosphate. Hence, P 4 O 10 can't be used for drying of NH 3. P 4 O 10+12 NH 3+6 H 2 O arrow 4( NH 4)3 PO 4

Q. $P_{4} O_{10}$ is not used to dry $N H_{3}$ gas because

$P_{4} O_{10}$ is not a drying agent

$P_{4} O_{10}$ reacts with moisture in $N H_{3}$

$P_{4} O_{10}$ is basic and $N H_{3}$ is acidic

none of these.

$P_{4} O_{10}$ is acidic and $N H_{3}$ is basic, so they react with each other in presence of moisture giving ammonium phosphate. Hence, $P_{4} O_{10}$ can't be used for drying of $N H_{3}$ .

$P_{4} O_{10} + 12 N H_{3} + 6 H_{2} O \to 4 (N H_{4})_{3} P O_{4}$
