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

A

`Cr(SO)_(4))_(3)`

B

`CrO_(4)^(2-)`

C

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

D

`CrSO_(4)`

Text Solution

Verified by Experts

The correct Answer is:
A
`K_(2)Cr_(2)o_(7)+3Na_(2)SO_(4)to`
`3Na_(2)SO_(4)+K_(2)SO_(4)+Cr_(2)(SO_(4))_(3)+4H_(2)O`
