Question

Drops of nitric acid reacts with $P_2{O}_5$ to gives :

• A. $NO$
• B. $N{O}_2$
• C. $N_2{O}_5$
• D. $HP{O}_3$

Answer 1

Answer: (C), (D)

The correct options are
C $N_2{O}_5$
D $HP{O}_3$

The reaction between nitric acid and $P_2{O}_5$ is as follows:

$2HN{O}_3+P_2{O}_5\to H_{2}O+N_2{O}_5$ --- 1

$H_{2}O+P_2{O}_5\to 2HP{O}_3$ ----- 2

Overall reaction:

$2HN{O}_3+P_2{O}_5\to N_2{O}_5+2HP{O}_3$
