Question

Define osmotic pressure. why does osmotic pressure become abnormal

Answer 1

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.

water actually flows out of the cell into the surrounding solution thereby causing the cells to shrink and lose its turgidity.


Osmotic pressure increases with the increase in temperature.
