`NaCl + K_(2)Cr_(2)O_(7)+H_(2)SO_(4) rarr NA_(2)SO_(4) + K_(2) SO_(4) +H_(2)O +X`
The oxidation state chromium in the product X

A

`+5`

B

`+6`

C

`+7`

D

`+8`

Text Solution

Verified by Experts

The correct Answer is:
B
`4NaCl + K_(2) Cr_(2) O_(7) + 3H_(2) SO_(4) rarr 2Na_(2) SO_(4)+K_(2)SO_(4) + 3H_(2)O + 2CrO_(2) Cl_(2)`
Thus X is `CrO_(2) Cl_(2)` chromyl chloride
`:. ` O.N. of Cr is ` +6`
