During the bleaching action of ${SO}_{2}$ , it is converted to

A
$H_{2} {SO}_{3}$
B
${SO}_{3}$
C
$H_{2} S$
D
$H_{2} {SO}_{4}$

Solution:

${SO}_{2}$ reacts with any coloured substance to release oxygen from the substance resulting in loss of colour.

${SO}_{2} + 2 H_{2} O \to H_{2} {SO}_{4} + 2 (H)$

The above reaction is bleaching action of ${SO}_{2}$ in which ${SO}_{2}$ is converted into $H_{2} {SO}_{4}$ .
