.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

1N

B

2N

C

3N

D

0.5N

Text Solution

Verified by Experts

The correct Answer is:
B
100 grams of `H_2O_2` -------- x grams of `H_2O_2` (pure)
3.4 grams of `H_2O_2 -----?`
`W = (3.4x)/100` gms (pure)
number of GEW.s of `KMnO_4 = H_2O_2`
`x xx 10^(-3) xx N = (3.4xx x)/100 xx 1/17 , N =2`
