.4 sample of `H_(2)O_(2)` solution containing `H_(2)O_(2)` by weight requires x ml of `KMnO_(4)` solution for completed oxidation under acidic condition. The formality of `KMnO_(4)` solution is

A

0.2 M

B

0.11 M

C

0.011 M

D

0.25 M

Text Solution

Verified by Experts

The correct Answer is:
B
Meq of `H_(2)O_(2)` = meq of `KMnO_(4)`
`=(1xx(y//100))/("Eq.wt")xx1000`
Meq of `KMnO_(4)=N(y)=(1xx(y//100))/(34//2)xx1000`
`=N=(10)/(17)`
Molarity = `("Normality")/(5)=(10//17)/(5)=(2)/(17)=0.117M`
