Question

The semipermeable membrane of any substance allows _______molecules to pass through it.
A. Solvent
B. Solute
C. Solution
D. Collide particles

Answer 1

Hint: We know, semi-permeable is used in the osmosis process. In the osmosis process, there is movement from less concentrated solution into a more concentrated one. So, it could be known which particles are allowed by the semi-permeable membrane.

Complete step by step answer:
a) First, let us know about the semi-permeable membrane. It is also termed as selectively permeable, or partially permeable membrane.
b) It means that it allows the movement of selected ions, or particles, and it is made up of gelatin like material.
c) Now, we are given the options of different types of particles, if we talk about solute particles, and colloidal particles, they are allowed to pass through a permeable membrane through the passive movement.
d) As we know, osmosis allows the movement of solvent particles like water through a semipermeable membrane, and it is mentioned that semi-permeable is used in osmosis.
e) The daily life examples of osmosis include the skin soaking up water, and plant soaking up water.
6) In the last, we can conclude that the semi-permeable membrane of any substance allows the solvent molecules to pass through it.

So, the correct option is A.

Additional Information:
Permeable membranes allow all materials to pass through it whereas Semipermeable allows some materials to pass through.

Note: Don’t get confused between the diffusion, and the osmosis. Diffusion is a process that allows the transport of certain molecules, or ions (solute); whereas in the osmosis there is movement of water (solvent) across a membrane.
