Question

Osmosis is the term used to refer specifically to the diffusion of water across a differentially or semipermeable membrane. Which is not correct about it?

• A. Osmosis is the movement of solvent from their high conc. to low conc. through S.P.M.
• B. Osmosis is the movement of solution from their low conc. to high conc. through S.P.M.
• C. Osmosis is the movement of solvent from lower ${\psi }_w$ to higher ${\psi }_w$ through S.P.M.
• D. Osmosis is the movement of solvent from high solute potential to low solute potential through S.P.M.

Answer 1

The correct option is B Osmosis is the movement of solution from their low conc. to high conc. through S.P.M.

Osmosis is diffusion of solvent (water) (not solution) from region of its high concentration to region of its low concentration through semi-permeable /selective permeable membrane (SPM).
Osmosis is the movement of solvent from higher ${\psi }_w$ to lower ${\psi }_w$ through S.P.M.
Osmosis is the movement of solvent from low solute potential to high solute potential through S.P.M.
