Which of the following satements is`//`are correct?

Options

A. In the reaction `H_(2)O_(2)+I_(2)rarrI^(ө)+?`
the missing product is `O_(2)`.
B. In the above reaction `(a)`, the missing product is `H_(2)O`
C. In the reaction `H_(2)O_(2)+Sn^(2+)rarrSn^(4+)+?`,
the missing product is `O_(2)`
D. In the above reaction `(c )`, the missing product is `H_(2)O`

Answer

A, D

Explanation

Since `I_(2)` is reduced to `I^(ө)`, so `H_(2)O_(2)` must be oxidised to `O_(2)` (Oxidation state of `O` is zero).
`H_(2)O_(2)+I_(2)rarr2I^(ө)+O_(2)+2H^(o+)`
d. `Sn^(2+)` is oxidised to `Sn^(4+)`, so `H_(2)O_(2)` must be reduced to `H_(2)O`. (Oxidation state of `O` is `-2`).
