Question

(a) What is the nature of the oxide $S{O}_2$? What happens when it is dissolved in water? Write the chemical equation of the reaction involved.
(b) What is the nature of the oxide $N{a}_{2}O$? What happens when it is dissolved in water? Write the chemical equation of the reaction involved.

Answer 1

(a) $S{O}_2$ is acidic in nature. When sulfur dioxide(SO₂) reacts with water(H₂O), it forms sulfurous acid (H₂SO₃).

SO₂ + H₂O $⟶$ H₂SO₃

(b) $N{a}_{2}O$ is a basic oxide. It forms NaOH on being dissolved in water.

$N{a}_{2}O+H_{2}O⟶NaOH+O_2$
