Current Question (ID: 10659)

Question:

$\text{The bleaching action of SO}_2 \text{ is due to its}$

Options:

1. $\text{Acidic property}$
2. $\text{Basic property}$
3. $\text{Reducing property}$ (Correct)
4. $\text{Oxidising property}$

Solution:

$\text{Hint: Oxidation of sulphur takes place.}$ $\text{Bleaching action of: Bleaching by sulphur dioxide is due to the process of reduction in the presence of moisture.}$ $\text{SO}_2 + 2\text{H}_2\text{O} \rightarrow \text{H}_2\text{SO}_4 + 2[\text{H}] \text{ (nascent)}$ $\text{The nascent hydrogen liberated in the reaction is responsible for bleaching the flower but when the flower comes in contact with air. It gets oxidized and become coloured.}$ $\text{Colour material} + [\text{H}] \rightarrow \text{Colourless air Colour}$
