Question

4.
For acquiring large surface area, solids are found in
1) finely combined state
2) finely divided state
3) Both (1) and (2)
4) None of the above
Which force's) is/are responsible for attracting the adsorbate particles on its surface?​

Answer 1

Answer:

Option 2 finely divided state.

Explanation:

The accumulation of molecular species at the surface rather than in the bulk of a solid or liquid is termed adsorption.

Adsorption is essentially a surface phenomenon.

So, solids in a finely divided state, have a large surface area and they act as good adsorbents.

Here, both Assertion and reason are correct but the reason for Solid in finely divided state acting as good adsorbents is because of the large surface area.

Answer 2

Answer:

For acquiring a large surface area, solids are found in a finely divided state.

Explanation:

• The accumulation of molecular species at the surface rather than within-side the bulk of a solid or liquid is called adsorption.

• Adsorption is basically a surface phenomenon.

• So, solids in a finely divided state, have a big surface area, and they act as top adsorbents.

• Adsorption is the adhesion of atoms, ions, or molecules from a gas, liquid, or dissolved solid to a surface.

• This technique creates a film of the adsorbate at the surface of the adsorbent.
• This technique differs from absorption, wherein a fluid (the absorbate) is dissolved with the aid of using or permeating a liquid or solid (the absorbent).

Therefore, for acquiring a large surface area, solids are found in a finely divided state.

Unbalanced attractive forces are responsible for attracting the adsorbate particles on their surface.
