Which one of the following is most readily absorbed on activated charcoal?

Which of the following is absorbed generally by activated charcoal?

Gases with higher critical temperatures are readily adsorbed. Thus 1gram of activated charcoal adsorbs more SO2 (critical temp. 630K) than methane (critical temp 190K) which is still more than dhiydrogen (critical temperature 33K).

What toxins does activated charcoal absorb?

Which is easily adsorbed to charcoal?

The substance which is getting adsorbed is known as adsorbate and on which surface adsorption is taking place is known as adsorbent.

Name of gas Critical temperature in Kelvin
Methane CH4 190
Carbon dioxide CO2 304
Hydrochloric acid HCl 324
Ammonia NH3 406

Which is adsorbed in minimum amount by the activated charcoal?

Here , hydrogen has the minimum critical temperature, (-240∘C) hence, is adsorbed in minimum amount.
