- Definition: Osmotic Pressure
- Definition: Tonicity
CISCE: Class 10
Definition: Osmotic Pressure
Osmotic pressure is the minimum pressure that must be exerted to prevent the passage of the pure solvent into the solution when the two are separated by a semi-permeable membrane.
or
Osmotic pressure of a solution is a measure of its tendency to take in water by osmosis.
CISCE: Class 10
Definition: Tonicity
Relative concentration of the solutions that determines the direction and extent of diffusion is called tonicity.
