With reference to hydrogen peroxide (H₂O₂), identify the statement that is not true:

1. It should be kept in plastic containers or in glass bottles lined with wax and stored away from light.
2. It must be protected from dust contamination.
3. It functions only as an oxidising agent.
4. It breaks down when exposed to light.

Correct answer: It functions only as an oxidising agent.

Solution

Hydrogen peroxide is versatile and can act as both an oxidizing and a reducing agent, depending on the reaction conditions, making the statement incorrect.
