mechanism of osmosis and its importance
Answers
Osmosis is the spontaneous net movement of solvent molecules through a semi-permeable membrane into a region of highersolute concentration, in the direction that tends to equalize the solute concentrations on the two sides.[1][2][3] It may also be used to describe a physical process in which any solvent moves across a semipermeable membrane (permeable to the solvent, but not the solute) separating two solutions of different concentrations.[4][5] Osmosis can be made to do work.[6]
Osmotic pressure is defined as the externalpressure required to be applied so that there is no net movement of solvent across the membrane. Osmotic pressure is a colligative property, meaning that the osmotic pressure depends on the molar concentration of the solute but not on its identity.
