50 ml H(2)O(2) is completely oxidised by...

50 ml `H_(2)O_(2)` is completely oxidised by 10 ml, 0.2 N `KMnO_(4)` solution in acidic medium. The strength of hydrogen peroxide is

A

0.68 gm/lit

B

`(M)/(50)`

C

`(N)/(25)`

D

`3.4%(w//v)`

Text Solution

Verified by Experts

The correct Answer is:
A, B, C
Eq. `H_(2)O_(2)` = eq. `KMnO_(4)`
`50xxN=10xx0.2`
`N=(0.2)/(5)=(1)/(25),M=(N)/(2)=(1)/(50)`
`M=(S)/("M.wt.")impliesS=(1)/(50)xx34=0.68g//L`
