osmotic

(Science: chemistry) Pertaining to or of the nature of osmosis (= the passage of pure solvent from a solution of lesser to one of greater solute concentration when the two solutions are separated by a membrane which selectively prevents the passage of solute molecules, but is permeable to the solvent).

How will conc. on 2 sides be equal when osmosis stops?

could you please explain why osmotic pressure will be equal since osmotic pressure is directly proportional to the centration of solute? and the air pressure is the same

How will conc. on 2 sides be equal when osmosis stops?

If the membrane is semipermeable and the solute cannot cross the membrane, the concentrations will not be the same. However, the osmotic pressure could be the same (if there was not only pure water, but some solution).
