प्रश्न
What happens when the external pressure applied becomes more than the osmotic pressure of solution?
Advertisements
उत्तर
When the external pressure exerted on the solution is higher than the osmotic pressure, the pure solvent starts flowing out of the solution through the semi-permeable membrane. This process is known as reverse-osmosis.
