Your question: Which gas is most absorbed by charcoal?

Which is maximum absorbed by the charcoal?

Answer: The gas that can be strongly adsorbed by charcoal is NH3. The reason behind this is that NH3 is easily liquifiable. Charcoal strongly absorbsthose compounds that are easily liquifiable, which is the case with ammonia or NH3.

What is the most adsorbed gas on activated charcoal?

Because it is easily absorbed. So that in the given four gases, more absorbed in activated charcoal is sulfur dioxide (SO2 ). Therefore,the correct option is (A).

Which gas is least absorbed on charcoal?

When we compare the molecular weights of the gases from each option, the gas with the minimum molecular mass is hydrogen (${H_2}$). So we can clearly say that it is the gas that will have a minimum amount of critical temperature so it will have minimum adsorption by activated charcoal.

Which will absorb more gas a lump of charcoal or its powder and why?

Powdered charcoal will adsorb more gas because of its larger surface area than a lump of charcoal.

Can I use charcoal instead of activated charcoal?

In theory, yes, you can use charcoal instead of activated charcoal. However, regular charcoal won’t be anywhere near as effective. You also could expose yourself to chemical additives or impurities.

What gases does charcoal absorb?

The gas that can be strongly adsorbed by charcoal is B) NH3.

The reason behind this is that NH3 is easily liquifiable. Charcoal strongly absorbs those compounds that are easily liquifiable, which is the case with ammonia or NH3. The gas can be easily liquefied because of more surface area.

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 gas absorbs least?

Answer: (d) Lesser the value of critical temperature of gases lesser will be the extent of adsorption. Here H2 has lowest value of critical temperature, i.e., 33. Hence, hydrogen gas shows least adsorption on a definite amount of charcoal.

What is absorbed minimum for activated charcoal?

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

Which absorbs more carbon monoxide charcoal lump or charcoal powder Why?

Which will adsorbe more a lump of charcoal or charcoal powder, and why? Answer: Adsorption is more in Charcoal powder because it has greater surface area, therefore greater Van der Waal’s attraction.

Which type of colloid is cheese?

Colloid is a solution that has particles ranging between 1 and 1000 nanometres. Cheese is a solid emulsion in which liquid is solute and solid is solvent. Hence, cheese is colloidal solution of liquid in solid.

What are the factor which influence the adsorption of a gas on a solid?

The greater the surface area of the adsorbent, the greater is the adsorption of a gas on the solid surface. Adsorption is a reversible process and is accompanied by a decrease in pressure. Therefore, adsorption increases with an increase in pressure.
