LoginWhat is a necessary condition for osmosis to take place?
(a) Semi-permeable membrane
(b) Same concentration of solvent
(c) High temperature
(d) Pressure greater than osmotic pressure
The question was asked at a job interview.
My question comes from Colligative Properties and Determination of Molar Mass in chapter Solutions of Chemistry – Class 12

Correct answer is (a) Semi-PERMEABLE membrane
The explanation is: A semi permeable membrane is a must CONDITION since it facilitates the blocking of solute particles from diffusing through and allows only water molecules to PASS through. Obviously, water is the solvent in osmosis hence the concentration of solvent cannot be same if osmosis has to occur. If pressure greater than osmotic pressure is applied, REVERSE osmosis takes place. MEANING, water molecules will flow from region of lower water potential to higher water potential.
