For completely reacting with 400 mL of 1 N acidified `KMnO_(4)` solution, what volume of a 10 volume sample of `H_(2)O_(2)` is needed?

A

56 mL

B

224 mL

C

28 mL

D

112 mL

Text Solution

Verified by Experts

The correct Answer is:
B
Normality of 10 vol. `H_(2)O_(2)=(3.035xx10)/(17)=1.785`
`N_(1)V_(1)=N_(2)V_(2)`
`1.785xxV_(1)=1xx400impliesV_(1)=(400)/(1.785)=224.08mL~~224mL`

Assertion If 10 mL of a H_(2)O_(2) solution required 8.00 mL of 0.02 M acidified KMnO_(4) solution for complete oxidation, 12.50 mL of same H_(2)O_(2) will oxidise completely to 5.00 mL of 0.10 M Na_(2)C_(2)O_(4) solution. Reason H_(2)O_(2) act as both oxidising as well as reducing agent.

When 2.5g of a sample of Mohr's salt reacts completely with 50mL of (N)/(10) KMnO_(4) solution. The % purity of the sample of Mohr's salt is:

A sample of MnSO_(4). 4H_(2)O is strongly heated in air. The residue ( Mn_(3)O_(4)) left was dissolved in 100 mL of 0.1NFeSO_94) containing dil. H_(2)SO_(4) . This solution was completely reacted with 50 mL of KMnO_(4) solution. 25 mL of this KMnO_(4) solution was completely reduced by 30 mL of 0.1N FeSO_(4) solution. Calculate the amount of MnSO_(4).4H_(2)O in sample.

20 ml of an H_2 O_2 solution on reaction with excess of acidified KMnO_4 released 224 cc of O_2 . What is the volume strength of that H_2 O_2 ?
