The volume strength of `1*5` N `H_(2)O_(2)` solution is

A

`4.8`

B

`8.4`

C

`3.0`

D

`8.0`

Text Solution

Verified by Experts

The correct Answer is:
B
`"Strength = Normality"xxEq. wt.`
`=1.5xx17=25.5gL^(_1)(.:'Eq.wt.ofH_(2)O_(2)=17)`
`underset(68g)(2H_(2)O_(2))to2H_(2)O+underset(22400mL)O_(2)`
`:'68g" of"H_(2)O_(2)" given " 22400mL O_(2)" at STP"`
`:.25.5g" of "H_(2)O_(2)" gives"(22400xx25.5)/(68)=8400mLO_(2)" at STP"`
`=8.4mL" of "O_(2)`
`:." Volume strength of "1.5NH_(2)O_(2)" solution"=8.4L`
