Woorksheet on Osmotic pressure





The pressure which is applied to a solution to prevent the inward flow of water across a semipermeable membrane is known as Osmotic pressure. Pressure which is required to stop osmosis is called Osmotic pressure.

In this article you can find some questions related to Osmotic pressure and their answers:
