A

`Na_(2)S_(2)O_(3)` is oxidised

B

`CuI_(2)` is formed

C

`Cu_(2)I_(2)` is formed

D

Text Solution

Verified by Experts

The correct Answer is:
B
`2overset(-1)(KI)+2CuSO_(4)rarroverset(0)I_(2)+Cu_(2)I_(2)+2K_(2)SO_(4)`
`overset(0)I_()+2Na_(2)overset(+2)S_(2)O_(3)rarroverset(+2.4)(Na_(2))S_(4)O_(6)+2overset(-1)(NaI)`
