The oxidation state of chromium in the final product formed by the reaction between Kl and acidified potassium dichromate solution is `:`

A

`+3`

B

`+2`

C

`+6`

D

`+4`

Text Solution

Verified by Experts

The correct Answer is:
A
`Cr_(2)O_(7)^(2+)+14H^(+)+6l^(-)rarr2Cr^(3+)+7H_(2)O+3l_(2)`
Thus , final state of Cr is `+3`.
