Question

Two solutions A and B are separated by a semipermeable membrane. If the solvent flows from A to B, then ____________.

Options

• A is more concentrated than B

• A is less concentrated than B

• both A and B have the same concentration

• the pressure should be applied on the side of solution A to prevent the flow of solvent

Answer 1

Two solutions A and B are separated by a semipermeable membrane. If the solvent flows from A to B, then A is less concentrated than B.

Explanation:

The solvent moves from a lower concentration solution to a higher concentration solution in osmosis. As a result, if the solvent flows from point A to point B, point A is less concentrated than point B. To stop the flow of solvent, apply pressure to the side with the highest concentration.
