Question

$H_2{O}_2$ acts as strong oxidising agent in:

• A. acidic medium
• B. in the presence of Glycerol
• C. alkaline medium
• D. neutral medium

Answer 1

The correct option is A acidic medium

To be a good oxidising agent, it should have a higher reduction potential.
In acidic medium, $E_{red}^0=+1.77$
In basic medium, $E_{red}^0=+0.87$
Hence it is a better oxidising agent in acidic medium.
