A) \[2{{S}_{2}}O_{3}^{2-}{{S}_{4}}O_{6}^{2-}\]
B) \[Z{{n}^{2+}}Zn\]
C) \[Cl{{O}^{-}}C{{l}^{-}}\]
D) \[S{{O}_{3}}SO_{4}^{2-}\]
Correct Answer: A
Solution :
In the reaction; \[{{S}_{2}}O_{3}^{2-}\xrightarrow{{}}{{S}_{4}}O_{6}^{2-};\] the oxidation state of sulphur changes from 2 to higher oxidation state 2.5. Thus, this change requires an oxidising agent.You need to login to perform this action.
