A) \[S{{n}^{2+}}\]
B) \[S{{n}^{4+}}\]
C) \[As\]
D) \[HAs{{O}_{2}}\]
Correct Answer: D
Solution :
Oxidizing agent, itself, undergoes reduction during a redox reaction reduction \[\overset{+3}{\mathop{HAs{{O}_{2}}}}\,+S{{n}^{2+}}\xrightarrow{{}}\overset{0}{\mathop{As}}\,+S{{n}^{2+}}+{{H}_{2}}O\] Hence, here \[HAs{{O}_{2}}\] is acting as oxidizing agent.You need to login to perform this action.
