Question

What is the difference between selectively permeable membrane and semipermeable membrane?

Answer 1

semipermeable membrane allows particles to pass through
selectively permeable membrane chooses what passes through

Answer 2

Answer:

(1) Permeable membrane: A membrane which allows free transfer of the solute molecules from a solution of a higher concentration to a solution of a lower concentration through it is called a permeable membrane and the transfer is called diffusion, e.g, a membrane of a paper.

(2) Semipermeable membrane : A membrane which allows free passage of only the solvent molecules but not the large solute molecules or 1ons of large molecular mass trom a solution of a lower concentration (or a pure solvent) to a solution of higher concentration through it, is called a semi-permeable membrane, e.g, parchment paper, complex like Cu[Fe (CN)s]. etc.
