Question
Which of the following molecules can act as an oxidizing as well as a reducing agent ?
Options
A.H2S
B.SO3
C.H2O2
D.F2
Solution
H2O2 can act both as an oxidising as well as a reducing agent.
Oxidising agent
pbS + 4H2O2 →
Reducing agent
Ag2O + H2O2 → 2Ag + H2O + O2
(moist)
Oxidising agent
pbS + 4H2O2 →

Reducing agent
Ag2O + H2O2 → 2Ag + H2O + O2
(moist)
