Question

Surface area per gram of the adsorbent is called?

• A. Molar surface area
• B. Normal surface area
• C. Specific surface area
• D. Equivalent surface area

Hint:

When studying adsorbents, always consider the specific surface area} to determine how much material will adsorb a particular substance. Higher values indicate better adsorbent properties.

Answer 1

The Correct Option is C

The term specific surface area refers to the surface area per unit mass of a material, typically measured in units of \({m}^2/{g}\). This is a critical property of materials such as adsorbents, as it gives an idea of how much surface area is available for adsorption per gram of the material.
For instance, when discussing adsorption, the specific surface area of the adsorbent plays a major role in determining how much of a substance can be adsorbed on the material’s surface. The higher the specific surface area, the greater the adsorptive capacity of the material.
The other terms listed in the options are:
- Molar surface area refers to the surface area per mole of a substance.
- Normal surface area doesn’t have a standard meaning in this context and is not typically used in material science or adsorption studies.
- Equivalent surface area could be a term used in specific contexts but does not apply as widely as specific surface area.
Thus, the correct answer is specific surface area.
