Given`:`
Oxidation`H_(2)O_(2) rarr O_(2)+2H^(o+)+2e^(-)" "E^(c-)=-0.69V,`
`2F^(c-)rarr F_(2)+2e^(-)" "E^(c-)=-287V,`
Reduction `: H_(2)O_(2)+2H^(o+)+2e^(-) rarr 2H_(2)O" "E^(c-)=1.77V,`
2I^(c-)rarr I_(2)+2e^(-)" "E^(c-)=-0.54V,`
Which of the following statements is `//` are correct ?

A

`H_(2)o_(2)` behaves as an oxidant for `I^(c-)`

B

`H_(2)O_(2)` behaves as a reductant for `1I_(2)`

C

`H_(2)O_(2)` behaves as an oxidant for `F^(c-)`

D

`H_(2)O_(2)` behaves as a reductant for `F_(2)`.

Text Solution

Verified by Experts

The correct Answer is:
a,d
Create a cell with required equation `(` cell reaction `)` and find its `E^(c-)._(cell)`
`e.g., (A):H_(2)O_(2)+I^(c-) rarr I_(2)+H_(2)O`
`E^(c-)._9cell)=(1.77)-(0.54)gt0`
`(B):H_(2)O_(2)+I_(2) rarr I^(c-)+O_(2)`
`E^(C-)._(cell)=(0.54)-(0.69)lt0`
`(` Not possible to occur spontaneously `)`
And so on.
