Why do solvent particles from the pure solvent move toward the solution side in the osmometer?
Due to difference in water concentration
Due to difference in solute concentration
Both a and b
None of these
The solvent particles move from the pure solvent move toward the solution side in the osmometer due to difference in water concentration. Osmosis never involves the movement of solute so their concentration is not considered. It always occurs as per the concentration gradient of the water molecules.
Hence, the correct answer is option a.
