In the conversion of `K_(2)Cr_(2)O_(7) "to K"_(2)CrO_(4)`, the oxidation number of chromium

A

remain same

B

increases

C

decrease

D

none of these

Text Solution

Verified by Experts

The correct Answer is:
A
Cr in `K_(2)Cr_(2)O_(7) rArr 2 + 2x - 14 = 0" ", " "x = 6`
Cr in `K_(2)Cr_(2)O_(4) rArr 2 + x - 8 = 0" "," "x = 6`
Here, oxidation number of Cr remains same when `K_(2)Cr_(2) O_(7)` changes into `K_(2)Cr_(2)O_(4)`.
