`x g` of `H_2O_2` requires `100mL` of `M//5 KMnO_4` in a titration in a solution having `pOH = 1.0` Which of the following is`//`are correct?

A

The value of `x`is `1.7 g`

B

The value of `x` is `0.34 g`

C

`MnO_(4)^(ɵ)` change to `MnO_(4)^(2ɵ)`

D

`H_(2)O_(2)` change to `O_(2)`

Text Solution

Verified by Experts

The correct Answer is:
B, C, D
`POH=1`, strong basic medium
`implies MnO_(4)^(ɵ)toMnO_(4)^(ɵ)` (`n`-factor=`1`)
`2overset(Theta)(O)H+H_(2)O_(2)toO_(2)+2H_(2)O+2e^(ɵ)`
`mEq of H_(2)O_(2)=mEq of MnO_(4)^(ɵ)`
`x/(34//2)xx1000=100xx[1/5xx1]`
`x=0.34 g`
