Question

Identify the gas which is readily adsorbed by activated charcoal

• A. $H_2$
• B. $O_2$
• C. $N_2$
• D. $SO_2$

Answer 1

Answer: (D)

$SO_2$

Answer 2

The correct answer is Option D) $SO_2$

A gas which is easy to liquefy is most readily adsorbed. This is because van der Waal's forces are stronger near critical temperatures.

380 ml of sulphur dioxide is readily adsorbed by 1g of activated charcoal. Thus out of the given four choices $SO_{2}$ will be most readily adsorbed

Therefore, Option D is the correct answer.
