Hydrogen Peroxide

Question

In which reaction, hydrogen peroxide neither acts as an oxidising agent nor as a reducing agent ?

Easy

A

PbS + H₂O₂ →
B

SO₃^-2 + H₂O₂ →
C

PbO₂ + H₂O₂ →
D

Na₂CO₃ + H₂O₂ →

Solution

H₂O₂ acts as O.A
H₂O₂ acts as O.A
H₂O₂ acts as R.A
H₂O₂ reduces the PbO₂ to PbO
$\large \mathop {N{a_2}}\limits^{ + 1} \mathop C\limits^{ + 4} \mathop {{O_3}}\limits^{ - 2} + \mathop {{H_2}}\limits^{ + 1} \mathop {{O_2}}\limits^{ - 1} \xrightarrow{{}}\mathop {N{a_2}}\limits^{ + 1} \mathop {{O_2}}\limits^{ - 1} + \mathop C\limits^{ + 4} \mathop {{O_2}}\limits^{ - 2} + \mathop {{H_2}}\limits^{ + 1} \mathop O\limits^{ - 2} \$
H₂O₂ neither acts as an oxidising agent nor as a reducing agent.
