Question

Which is not a characteristic of imbibition?

• A. It is a reversible phenomenon
• B. It involves diffusion
• C. Involves adsorption
• D. It is a property of hydrophobic colloids

Answer 1

The correct option is D It is a property of hydrophobic colloids

Imbibition is a special type of diffusion that takes place when water is adsorbed by solids-colloids causing an increase in volume. Examples include the absorption of water by seeds and dry wood. It is a reversible process. It is the absorption of water by general surface.

Hydrophobic colloids do not interact with water. So, imbibition is not a property of hydrophobic colloids.
