`5.0 cm^(3)` of `H_(2)O_(2)` liberates 0.508 g of iodine from an acidified KI solution. The strength of `H_(2)O_(2)` solution in terms of volume strenth at STP is

Explanation

m" Eq of "`I_(2)=(0.508)/(127)xx1000`
m" Eq of "`KI=(0.508)/(127)xx1000`
m" Eq of "`H_(2)O_(2)=(0.508)/(127)xx1000`
Normality of `H_(2)O_(2)=(0.508)/(127)xx(1000)/(5)`
for `H_(2)O_(2)`,
`5.6xx` Normality`=` Volume strength
`therefore` Volume strength`=(0.508)/(127)xx(1000)/(5)xx5.6=4.48V`
