An excess of `Na_(2)S_(2)OO_(3)` react with aqueous `CuSO_(4)` to give

A

`CuS_(2)O_(3)`

B

`Cu_(2)S_(2)O_(3)`

C

`Na_(2)[Cu(S_(2)O_(3))_(2)]`

D

`Na_(4)[Cu_(6)(S_(2)O_(3))_(5)]`

Text Solution

Verified by Experts

The correct Answer is:
4
`CuSO_(4)+Na_(2)S_(2)O_(3)rarrCuS_(2)O_(3)+Na_(2)SO_(4)`
`2CuS_(2)O_(3)+Na_(2)S_(2)O_(3)rarrCu_(2)S_(2)O_(3)+Na_(2)SO_(4)O_(6)`
`3Cu_(2)S_(2)O_(3)+2Na_(2)SO_(3)rarrNa_(4)[Cu_(6)(S_(2)O_(3))_(5)]`
