Question

Give reasons of the following:
$N_{2} O_{5}$ is more acidic than $N_{2} O_{3}$ .

Open in App

Solution

$N_{2} O_{5}$ is more acidic because it form $H N O_{3}$ with $H_{2} O$ and while $N_{2} O_{3}$ forms $H N O_{2}$ with $H_{2} O$ . $H N O_{3}$ is a stronger acid than $H N O_{2}$ .

$N_{2} O_{5} + H_{2} O \to 2 H N O_{3}$

$N_{2} O_{3} + H_{2} O \to 2 H N O_{2}$
