A 5.0 mL solution of H(2)O(2) liberates ...

A 5.0 mL solution of `H_(2)O_(2)` liberates 1.27 g of iodine from an acidified KI solution. The percentage strenth of `H_(2)O_(2)` is

A

2.24 V

B

1.12 V

C

4.48 V

D

8.96 V

Text Solution

Verified by Experts

The correct Answer is:
C
meq `H_(2)O_(2)=` meq `I_(2)`
`Nxx5=(0.508xx2)/(254)xx1000` or Normality = 0.8 N
Volume strength = `5.6xxN=5.6xx.8=4.48 V`.
