Question

How does the change in osmolarity influence the change in volume of water on either side of a selectively permeable membrane?

Answer 1

Ans. The selectively permeable membrane is a membrane which allow some special substances to pass through it and does no allow other substances like the larger particles. That's why it is called as the selectively permeable membrane .

It allows water to pass through it or the solvent molecules can pass through it . It does not allows the other ions and larger molecules to pass through it.

When the osmolarity around the semi permeable membrane changes, it will also change the volume of water on either sides of the membrane. If osmolarity on one side is higher, water molecules or water volume will also moves towards that sides, hence it will have the more water volume. And the other side will have the less water.
