Question 6
Which among the following defines osmosis the best?
(a) Movement of water molecules from a region of higher concentration to a region of lower solute concentration through a semipermeable membrane
(b) Movement of solvent molecules from its higher concentration to a lower concentration
(c) Movement of solvent molecules from a higher concentration to a lower concentration of solution through a permeable membrane
(d) Movement of solute molecules from a lower concentration to a higher concentration of a solution through a semipermeable membrane
(a) Movement of water molecules from a region of higher concentration to a region of lower solute concentration through a semipermeable membrane
Osmosis is a process by which the molecules of a solvent pass from a solution of low concentration to a solution of high concentration through a semi-permeable membrane. It is a passive process and happens without any expenditure of energy.
