Question

what is osmosis ? Describe it briefly.


please give answer fast ...​

Answer 1

Osmosis is the spontaneous net movement of solvent molecules through a selectively permeable membrane into a region of higher solute concentration, in the direction that tends to equalize the solute concentrations on the two sides.It may also be used to describe a physical process in which any solvent moves across a selectively permeable membrane (permeable to the solvent, but not the solute) separating two solutions of different concentrations. Osmosis can be made to do work.Osmotic pressure is defined as the external pressure 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.

Answer 2

Osmosis is the movement of particles from higher concentration to lower concentration through semi permeable membrane.

It is of two types

1.Exosmosis -It is movement of solute particles from inside to outside

For example-When raisins are put in a liquid., it swells due to exosmosis

2.Endosmosis-It is the movement of solute particles from outside to inside.

For example- When swelled raisins are the in salt solution it shrinks due to end osmosis..
