Question

Define Osmosis and Osmotic pressure.

Answer 1

Osmotic pressure is the minimumpressure which needs to be applied to a solution to prevent the inward flow of its pure solvent across a semipermeable membrane. It is alsodefined as the measure of the tendency of a solution to take in pure solvent (which belongs to the solution under discussion) by osmosis.

Answer 2

Osmosis is the process of the movement of water molecules from the region of their lower concentration to the region of their higher concentration...
Osmotic pressure is the min pressure that must be exerted to prevent the passage of pure solvent into the soln during separation by a membrane...
