Acidified `K_(2)Cr_(2)O_(7)` solution turns green when `Na_(2)SO_(3)` is added to it. This is due to the formation of

A

`CrSO_(4)`

B

`Cr_(2)(SO_(4))_(3)`

C

`CrO_(4)^(2-)`

D

`Cr_(2)(SO_(3))_(3)`

Text Solution

Verified by Experts

The correct Answer is:
B
`K_(2)Cr_(2)O_(7)+3Na_(2)SO_(3)+4H_(2)SO_(4)rarr 3Na_(2)SO_(4)+K_(2)SO_(4)+Cr_(2)(SO_(4))_(3)`
