Question

The reaction between dinitrogen trioxide and potassium hydroxide gives $KN{O}_2$.
$N_2{O}_3+2KOH\to 2KN{O}_2+H_{2}O$

What can we conclude about the nature of dinitrogen trioxide?

• A. It is acidic oxide
• B. It is basic oxide
• C. It is amphoteric oxide
• D. It is neutral oxide

Answer 1

The correct option is A It is acidic oxide

$N_2{O}_3+2KOH\to 2KN{O}_2+H_{2}O$

In the above reaction, we can see that dinitrogen trioxide is an acidic oxide, as $N_2{O}_3$ reacts with a base $\left(KOH\right)$ to form salt and water. This is the characteristic of acidic oxide.

Hence, option $A$ is correct.
