Question

How Osmosis - a special case of diffusion? ...!?!?

Answer 1

$\huge\underline\mathcal\red{Answer}$

→ Diffusion is a net movement of particles of substances from its higher concentration to its lower concentration.

In osmosis, movement of water occurs but across a semi permeable membrane.

Here, in this case, also movement takes place from higher to lower concentration obeying the rules of diffusion.

The speciality is this the movement is only of water. So it seems a special case of diffusion in which water moves across a semi permeable membrane.

Answer 2

Answer:

• Osmosis is a special case of diffusion as it involves water molecules.

• Osmosis takes place when water molecules move from a higher concentration area to a lower concentration area across a semi permeable membrane. Thus, it can be concluded that when water is involved, its diffusion is called osmosis.

• Osmosis is similar to simple diffusion, but it describes water molecules moving across a membrane. Simple Diffusion is a process by which molecules of gas or liquid move from an area of high concentration to low concentration until equilibrium is achieved.
