What is the equivalent mass of IO4^(-) ...

What is the equivalent mass of ` IO_4^(-)` when it is converted into `I_2` in acid medium ?

A

`M//6`

B

`M//7`

C

`M//5`

D

`M//4`

Text Solution

Verified by Experts

The correct Answer is:
B
`underset((O.N. of I = +7))(IO_(4)^(-))+8H^(+)tounderset((O.N. of I=0))(I_(2))+4H_(2)O-7e^(-)`
Eq. mass of `O_(4)^(-) = ("Mol mass")/(7) = (M)/(7)`
