Current Question (ID: 18125)

Question:

$\text{If 'A' contains 2 \% NaCl and is separated by a semi permeable membrane from 'B', which contains 10 \% NaCl, then the event that will occur is}$

Options:

1. $\text{NaCl will flow from 'A' to 'B'}$
2. $\text{NaCl will flow from 'B' to 'A'}$
3. $\text{Water will flow from 'A' to 'B'}$
4. $\text{Water will flow from 'B' to 'A'}$

Solution:

$\text{Hint- In osmosis flow of solvent takes place only}$ $\text{Explanation}$ $\text{Osmosis is the spontaneous net movement or diffusion of solvent molecules through a selectively permeable membrane from a region of high water potential to a region of low water potential, in the direction that tends to equalize the solute concentrations on the two sides.}$ $\text{2\% NaCl solution (A) separated by semipermeable membrane from 10\% NaCl solution (B). Then from dilute solution to conc. solution solvent flow.}$ $\text{2\% NaCl solution is more diluted than 10\% NaCl solution. Hence, movement of solvent takes place from 2\% NaCl solution to 10\% NaCl solution.}$
