Question

In the figure given below:-

Since only solvent particles can move through semipermeable membrane, if we manage to keep pressure on both the containers equal say by keeping weights, will osmosis go on till pure solvent container reaches zero volume?

Answer 1

In osmosis, solvent molecules diffuse through a semipermeable membrane from an area of lower concentration to an area of higher concentration. The solvent will continue to move until the concentrations on both sides are equal, but will not reach zero volume due to the osmotic pressure of the solution.

Step-by-step explanation:

Osmosis is the process by which solvent molecules selectively pass through a semipermeable membrane from an area of lower concentration to an area of higher concentration, diluting the concentrated solution. In an apparatus with two containers separated by a semipermeable membrane, the solvent will continue to move from the pure solvent container to the solution container until the concentrations on both sides are equal. However, it will not reach zero volume because the osmotic pressure of the solution will eventually equalize the pressure and stop the osmosis process.
