Identify the equations involved in bleaching action of \( \boldsymbol{S O}_{2} \)
- A. \( S O_{2}+H_{2} O \rightarrow H_{2} S O_{3} \)
- B. \( S O_{2}+O_{2} \rightarrow S O_{3} \)
- C. \( S O_{2}+2 H_{2} O \rightarrow H_{2} S O_{4}+2[H] \)
- D. \( S O_{3}+H_{2} O \rightarrow H_{2} S O_{4} \)
Step-by-step solution
Bleaching action of SO2 is due to its reducing property. It reacts with water to produce nascent hydrogen ([H]), which reduces colored compounds to colorless ones. This equation represents that reductive bleaching mechanism.
