In acidic medium potassium dichromate acts as on oxidant according to the equation,
`Cr_(2) O + 14 H^(+) + 6e^(-)rarr 2Cr^(3+) + 7H_(2)O`. What is the equivalent weight of `K_(2) Cr_(2) O_(7)`? (mol. `Wt. = M)`

A

`M`

B

`M//2`

C

`M//3`

D

`M//6`

Text Solution

Verified by Experts

The correct Answer is:
D

Since it accept `6 e^(-)` its
Equivalent weight `= (M)/(6)`
