$SO_2$

Vedclass · Answer

(B) Bleaching agents work by releasing nascent oxygen or by reduction. $H_2O_2$ acts as a bleaching agent by releasing nascent oxygen: $H_2O_2 \rightarrow H_2O + [O]$. $O_3$ acts as a bleaching agent by releasing nascent oxygen: $O_3 \rightarrow O_2 + [O]$. $Cl_2$ in the presence of moisture produces nascent oxygen: $Cl_2 + H_2O \rightarrow 2HCl + [O]$. $SO_2$ acts as a bleaching agent by reduction,but it is typically used for bleaching delicate materials like wool and silk. However,in the context of standard chemistry questions regarding common bleaching agents,all the listed options are actually used as bleaching agents. Given the standard curriculum,if one must be chosen as 'not used' in a specific context,it is often a trick question; however,all four are technically bleaching agents. Assuming the question implies which one is not a permanent bleaching agent or acts differently,$SO_2$ is a reducing agent,while the others are oxidizing agents. Since all are bleaching agents,this question is technically flawed,but $SO_2$ is the most distinct due to its reducing nature.
