Identify example of sorption from following.
Identify example of sorption from following.
Show Hint
Sorption = Adsorption + Absorption.
Updated On: May 14, 2026
- Charcoal is added to methylene blue solution.
- Chalk is dipped in ink.
- Hydrogen gas is passed over platinum
- Oxygen gas is passed over finely divided nickel.
Show Solution
Verified By Collegedunia
The Correct Option is B
Solution and Explanation
Step 1: Concept Sorption is a process where both adsorption (surface phenomenon) and absorption (bulk phenomenon) occur simultaneously.
Step 2: Meaning In such cases, the substance is concentrated on the surface and also enters the interior of the material.
Step 3: Analysis When chalk is dipped in ink, the solvent (water) is absorbed into the bulk of the chalk, while the pigment (color) is adsorbed on the surface.
Step 4: Conclusion This simultaneous action makes the dipping of chalk in ink a classic example of sorption. Final Answer: (B)
