The oxidation state of final product for...

The oxidation state of final product formed by the reaction between Kl and acidifed potassium dichromate solution is :

A

`+4`

B

`+6`

C

`+2`

D

`+3`

Text Solution

Verified by Experts

The correct Answer is:
D
`Cr_(2)O_(7)^(2-) + 14H^(+) + 6I^(-) to 2Cr^(3+) + 3I_(2) + 7H_(2)O`
oxidation of Cr is + 3 in the final product.
`underset("Calomel")Hg_(2)Cl_(2) + 2NH_(3) to Hg + Hg(NH_(2)) Cl + NH_(4)Cl`
