Step-by-step explanation:
Osmotic pressure is the maximum pressure developed in a solution, when it is separated from its pure solvent by a semi -permeable membrane.It is required to prevent entry of solvent across the semi-permeable membrane.Higher the concentration of the solute, greater will be the osmotic pressure required to prevent water.

- Osmotic pressure can be defined as the minimum pressure that must be applied to a solution to halt the flow of solvent molecules through a semipermeable membrane (osmosis).
- It is a colligative property and is dependent on the concentration of solute particles in the solution.
Osmotic pressure can be calculated with the help of the following formula:
Where,
- π is the osmotic pressure
- i is the van’t Hoff factor
- C is the molar concentration of the solute in the solution
- R is the universal gas constant
- T is the temperature
