NEET 2014 · Chemistry · p Block Elements (Group 15, 16, 17 & 18)

(a) H _ 2 O _ 2 + O _ 3 → H _ 2 O + 2 O _ 2 (b)H _ 2 O _ 2 + A g _...

\left(a\right){H}_{2}{O}_{2} + {O}_{3} \to {H}_{2}O + 2{O}_{2}

{\left(b\right)H}_{2}{O}_{2} + A{g}_{2}O \to 2Ag + {H}_{2}O + {O}_{2}

Role of hydrogen peroxide in the above reactions is respectively:

Options

AOxidizing in $\left(a\right)$ and reducing in $\left(b\right)$
Breducing in $\left(a\right)$ and oxidizing in $\left(b\right)$
Creducing in $\left(a\right)$ and $\left(b\right)$
Doxidizing in $( a )$ and $\left(b\right)$

Correct answer

C. reducing in $\left(a\right)$ and $\left(b\right)$

Step-by-step solution

${O}_{3}$ is reduced into ${O}^{- 2}$ ion and
A{g}_{2}O $is reduced to$ Ag $so<br />$ {H}_{2}{O}_{2}is reducing agent in $both \left(a\right) and \left(b\right)</p></blockquote>$
