`25 mL` of `0.50M H_(2)O_(2)` solution is added to `50 mL` of `0.20 M KMnO_(4)` is acid solution. Which of the following statements is true?

A

`0.010` mole of oxygen is liberated

B

`0.005` mole of `KMnO_(4)` are left

C

`0.030 g` atom of oxygen is liberated

D

`0.0025` mole of `H_(2)O_(2)` does not react with `KMnO_(4)`

Text Solution

Verified by Experts

The correct Answer is:
B

Meq.of `H_(2)O_(2)=25xx0.5xx2=25`,
Meq.of `KMnO_(4)=50xx0.2xx5=50`,
`:. 25 "Meq." or 5` milli-mole of `KMnO_(4)` are left.
