Which one of the following is present in gas mask?
- A Silica gel
- B \(\mathrm{V}_2 \mathrm{O}_5\)
- C Activated charcoal
- D Fluorescein
Answer & Solution
Correct Answer
(C) Activated charcoal
Step-by-step Solution
Detailed explanation
Activated charcoal is present in gas mask because it is a very good adsorbent. It can easily adsorb large volumes of gases, hence it is used in gas masks to adsorb harmful gases. It cannot adsorb oxygen which makes it perfect for gas masks.
