`i) H_2O_2 + O_3 to H_2O + 2O_2 " " ii) H_2O_2 + Ag_2O to 2Ag + H_2O + O_2`
Role of hydrogen peroxide'in the above reactions is respectively:

Options

A. oxidizing in(i) and reducing in(ii)
B. reducing in (i) and oxidizing in (ii)
C. reducing in (i) and (ii)
D. oxidizing in(i) and (ii)

Answer

C

Explanation

`I) H_2 O_2` is oxidised and thus reductant,` (O^(-1))_2 to (O^0)_2 + 2E^(-) `
`(ii) Ag_2 O` is reduced and thus `H_2O_2` is reductant, `Ag^(+) +e^(-) to (O^(0))_2 +2e^(-)`
