Explain each of the following statements and in each give it's balanced chemical equation, sulphur dioxide in solution acts as a bleaching agent ?

Sulphur dioxide in solution acts as a bleaching agent because it is able to react with colored compounds and break them down, resulting in the removal of the color. This is due to the reducing properties of sulphur dioxide, which allows it to donate electrons to the colored compounds, causing them to lose their color.

Balanced chemical equation:
SO2 + H2O → H2SO3
H2SO3 + colored compound → colorless compound + SO2 + H2O
