Chemistry Question on Redox reactions
Which of the following is not a reducing agent?
A
SO2
B
H2O2
C
CO2
D
Al
Answer
CO2
Explanation
Solution
CO2 is not a reducing but an oxidizing agent. SO2 and H2O2 act both as reducing as well as an oxidizing agent while Al is a reducing agent.
- An oxidizing agent causes oxidation as it accepts electrons; hence, it gets reduced.
- A reducing agent causes reduction by losing electrons; hence it gets oxidized.
Hence, Option C is the correct answer.
