define osmatic why does osmatic pressure become abnormal |
|
Answer» Ans :- 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. It is also defined as the measure of the tendency of a solution to take in pure solvent by osmosis. Osmotic pressure is a colligative property I.e. it depends upon number of particles of solute present in the solution. In case of solute which undergo association or dissociation, osmotic pressure is not normal ,it is more or less than the expected. |
