Question

what do you mean by osmotic pressure?

Answer 1

Osmotic pressure is the hydrostatic pressure developed in an osmotically active solution when it is separated from a pure solvent.

To make your concept clear, I have another definition: It is the minimum amount of pressure required to stop the solvent molecules from the hypotonic solution enter I to the hypertonic solution through the semi permeable membrane............

Answer 2

Osmotic pressure is the minimum pressure which needs to be applied to a solution to prevent the inward flow of its pure solvent across a semipermeable membrane...
