Imbibition and Imbibition Pressure -
- It is a special type of diffusion through which water is absorbed by certain substances like colloids, making them increase in volume.
- The classical example of imbibition is absorption of water by seeds and dry woods.
- The water is actually adsorbed first on the surface of the substances.
- An adsorbent is necessary for the process of imbibition.
- For any substance to imbibe any liquid, the affinity between the adsorbent and the liquid is also a prerequisite.
- For example, the rubber will not show imbibition when placed in water but when the wood is placed in water, the imbibition will occur.
- Proteins are efficient imbibants, followed by starch. Cellulose shows the least imbibing property.
- Proteinaceous seeds swell more on imbibition as compared to starchy seeds.
Proteins are efficient imbibants, followed by starch. Cellulose shows the least imbibing property. Hence, the correct answer is option c.
