Equivalent weight of `K_(2)Cr_(2)O_(7)` in the following reaction is
`Cr_(2)O_(7)^(2-)Fe^(2+) rarr Fe^(3+)Cr^(3+)`
(`M=molar mass` of `K_(2)Cr_(2)O_(7)`)

A

`(M)/(3)`

B

`(M)/(6)`

C

`(M)/(5)`

D

`(M)/(4)`

Text Solution

Verified by Experts

The correct Answer is:
B

Thus, equivalent weight of
`K_(2)Cr_(2)O_(7)=(molar mass)/(chang e I n ON)=(M)/(6)`
