In acidic medium, equivalent weight of `K_(2)Cr_(2)O_(7)` (molecular weight `= M`) is

A

`M//3`

B

`M//4`

C

`M//6`

D

`M//2`

Text Solution

Verified by Experts

The correct Answer is:
C
`Cr_(2)O_(7)^(2-)+14 H^(+)+6e rarr 2Cr^(3+)+7 H_(2)O`
Equivalent weight of `K_(2)Cr_(2)O_(7)`
`=("Molecular Mass")/6=294.2/6=M/6`.
