Question

How is osmosis related to diffusion?

Answer 1

Diffusion and osmosis are termed as the processes which are known to take place to equalize the concentration of two solutions. The movement of particles (solute and solvent) occurs one part to another part.

Complete answer:
1.Osmosis is termed as the movement of the water molecules that occurs from a region of higher concentration to a region of lower concentration with the help of a semipermeable membrane.
2.A semipermeable membrane is termed as a membrane that helps only water to pass through and not the solute.
3.Diffusion is defined as the process in which molecules of a substance transports from the place of their higher concentration to the place of their lower concentration (no membrane is required). Thus
diffusion that takes place by a semipermeable membrane is a special type of diffusion and it is termed osmosis. It is variable from the diffusion of water through permeable membranes.
4.From all these statements we gave above we can conclude that "Osmosis is a special kind of diffusion".

Diffusion takes place in liquids and gases because their particles move randomly from place to place, as they have weak molecular interaction then solid. So in this way osmosis is related to the diffusion by saying specialised diffusion.

Note: Examples of osmosis that includes - Swelling up of a raisin on keeping in water, Earthworm dying on that comes in connection with common salt, Shrinking of grapes kept in thick sugar syrup, Preserving pickles in salt.
