Current Question (ID: 18130)

Question:

$\text{During osmosis, the flow of water through a semi-permeable membrane is:}$

Options:

1. $\text{From a solution having higher concentration only.}$
2. $\text{From both sides of the semi-permeable membrane with equal flow rates.}$
3. $\text{From both sides of the semi-permeable membrane with unequal flow rates.}$
4. $\text{From a solution having lower concentration only.}$

Solution:

$\text{Hint: Use osmosis phenomenon.}$ $\text{Explanation:}$ $\text{Osmosis is the phenomenon of flow of pure solvent from the solvent to the solution or from a less concentrated solution to a more concentrated solution through a semipermeable membrane.}$ $\text{Common semipermeable membranes are permeable to certain solute particles also.}$ $\text{In fact, there is no perfect semipermeable membrane.}$ $\text{Therefore we can say that flow of water through a semipermeable membrane takes place both sides with unequal rates.}$ $\text{Osmosis is a bilateral process involving the movement of solvent particles through the semipermeable membrane and only net flow (more from dilute solution to conc. Solution) is noticed.}$
