Osmosis vs. Imbibition: What's the Difference?
Edited by Sawaira Riaz || By Sumera Saeed || Updated on October 26, 2023
Osmosis is the diffusion of water across a semipermeable membrane, while imbibition is the absorption of water by solids.
Key Differences
Osmosis and imbibition are both water movement processes, but osmosis involves a semipermeable membrane while imbibition doesn't.

Osmosis is a selective process, allowing only water molecules to pass through the membrane. Imbibition involves water being absorbed by porous solids.

In osmosis, water moves from a region of low solute concentration to high concentration. Imbibition occurs when water is drawn into a dry substance.

Osmosis
Diffusion of fluid through a semipermeable membrane from a solution with a low solute concentration to a solution with a higher solute concentration. Osmosis ceases when there is an equal solute concentration on both sides of the membrane.
