Question
Define osmatic pressure.
Solution
Answer:
Osmotic pressure is the minimum pressurewhich needs to be applied to a solution to prevent the inward flow of water across a semipermeable membrane. It is also definedas the measure of the tendency of a solution to take in water by osmosis.
or
osmotic pressure is proportional to the molarity, C of the solution at a given temperature T. Thus:
Π = C R T
Here Π is the osmotic pressure and R is the
gas constant.
