give a tabular difference between diffusion and osmosis
Answers
Answer
Osmosis is the movement of solvent particles across a semipermeable membrane from a dilute solution.
Diffusion is the movement of particles from an area of higher concentration to lower concentration. The overall effect is to equalize concentration throughout the medium.
Osmosis Diffusion
1) It is limited only to the liquid medium. 1) Occurs in liquid, gas and even solids.
2) Requires a semipermeable membrane. 2) Does not require a semipermeable membrane.
3) Depends on the number of solute particles dissolved. 3) Depends on the presence of other particles.
4)Requires water for the movement of particles. 4) Does not require water for the movement of particles.
5)Only the solvent molecules can diffuse. 5)Both the molecules of solute and solvent can diffuse.
6)The flow of particles occurs only in one direction. 6) The flow of particles occurs in all the directions.
7)The entire process can either be stopped or reversed 7)This process can neither be stopped nor reversed.
by applying additional pressure on the solution side.
8)Occurs only between similar types of solutions. 8) Occurs between the similar and dissimilar types of solutions.
