Describe the movement of water when a dialysis bag containing a 0.2 M sucrose solution is placed into distilled water. Assume sucrose cannot cross the semi-permeable membrane.

Answer :

Final answer:

When a dialysis bag containing a 0.2 M sucrose solution is placed in distilled water, water moves into the bag due to osmosis. This movement occurs because distilled water has a lower solute concentration compared to the sucrose solution. The process continues until the concentrations are balanced or pressure equals the osmotic force.


Explanation:

Movement of Water in Dialysis

When a dialysis bag containing a 0.2 M sucrose solution is placed in distilled water, the principle of osmosis comes into play. Osmosis is the movement of water across a semipermeable membrane from a region of lower solute concentration to a region of higher solute concentration.

In this scenario, the distilled water has a lower concentration of solutes (0 M for an effective comparison with the sucrose solution) compared to the 0.2 M sucrose solution inside the dialysis bag. Since sucrose cannot pass through the semipermeable membrane, water molecules will migrate from the outside (distilled water) into the bag to balance the concentration on both sides of the membrane.

This will result in an increase in the volume of the solution inside the dialysis bag as water enters, leading to a possible increase in weight of the bag when measured. The flow of water will continue until the concentration of solutes is equalized, or the pressure from the increased fluid level offsets further water movement.

Conclusion

Overall, the movement of water occurs from the distilled water into the dialysis bag, increasing the volume of fluid inside the bag, due to the principle of osmosis.
