Question

The movement of solvent molecules from higher concentration to lower concentration through semipermeable membrane under pressure is termed:

• A. osmosis
• B. reverse osmosis
• C. dialysis
• D. diffusion

Answer 1

Answer: (B)

reverse osmosis

$\begin{array}{c}\text{Osmosis: Movement of solvent molecules from lower concentration to higher concentration}\\ \text{through semipermeable membrane}\\ \\ \text{Dialysis - Separation of Particles in a Liquid on the basis of differences in their ability to}\end{array}$

$\begin{array}{c}\text{pass through a membrane}\\ \\ \text{Diffusion - Movement of molecules from higher pressure to lower pressure}\\ \\ \text{Hence option B is corrrect.}\end{array}$
