If the mass of each dialysis bag shown in the experimental set-up below is measured before each is immersed in its respective so
1 answer:
From the understanding of hypertonic, hypotonic, and isotonic solutions; one can deduce which of the dialysis bags will show the greatest increase in mass. The correct answer would be the dialysis bag with 1.0 M solution.
Hypertonic solutions have higher concentrations than the sap of whatever cell or substances that is put into them. Water molecules will move from the sap of any cell drop into such solutions into the solutions.
Isotonic solutions have the same concentration as the sap of cells drop into them. Hence, no net movement of water molecules by osmosis.
Hypotonic solutions have lower concentrations than the sap of cells drop into them. Hence, water will move from such solutions to the sap of the cells drop into them.
In the images, there are 3 categories of solutions:
- Hypertonic solutions: the solutions with 1.0, 0.4, and 0.6 M concentrations. The dialysis bags with 0.2 M solutions will lose water to their respective surrounding hypertonic solutions. Hence, their weights would decrease.
- Isotonic solution: the solution with 0.2 M concentration, the same concentration as the solution in the dialysis bag. The dialysis bag will neither gain nor lose weight.
- Hypotonic solution: the solution with 0.2 M concentration but the concentration of the solution in the dialysis bag is 1.0 M. Water molecules will move from the surrounding solution into the solution in the dialysis bag. Hence, the dialysis bag in this case will gain weight.
In other words, the dialysis bag with 1.0 M solution will have the greatest increase in mass due to a gain in water molecules by osmosis.
