Question

In the phenomenon of osmosis through the semipermeable membrane

Answer 1

• In the phenomenon of osmosis through the semi-permeable membrane pure water flows from the dilute solution to a higher concentrated solution.

• In other words, it can be defined as the movement of solvent molecules from a region of their high concentration to a region of their lower concentration across a semipermeable.

• Semi-permeable is the membrane that allows small molecules and ions to pass through it but acts as a barrier to larger molecules or dissolved substances.

Answer 2

Options are not provided in the question. The complete question is as following:

In the phenomenon of osmosis through the semipermeable membrane

A. solvent molecules pass from solution to solvent

B. solvent molecules pass from solvent to solution

C. solute molecules pass from solution to solvent

D. solute molecules pass from solvent to solution

Answer:

Osmosis always takes place across a semipermeable membrane.

Explanation:

Osmosis is defined as the phenomenon in which solvent particles moves across semipermeable membrane towards the solution with higher concentration of solute or lower concentration of solvent.

For example: when a animal or plant cell is placed in a salt solution, the solvent molecules moves through the cell membrane from less concentrated solution (inside the cell) into a more concentrated solution (outside the cell) that is salt water and cell will shrink.

Hence, the correct option is B. solvent molecules pass from solvent to solution.
