What would happen if a dialysis bag filled with surcrose and then placed in distilled water?
If a dialysis bag filled with sucrose is placed in distilled water, water will move into the bag through osmosis, as the concentration of sucrose inside the bag is higher than that of the distilled water outside. This influx of water will cause the bag to swell and potentially burst if the pressure exceeds the bag's capacity. Since sucrose molecules cannot pass through the dialysis membrane, they will remain inside the bag, creating a concentration gradient that drives the osmotic movement of water.
How could you prove or disprove that a specific solute such as sucrose was able to diffuse through a semi-permeable membrane?
To prove that sucrose can diffuse through a semi-permeable membrane, you could set up an experiment using a dialysis bag filled with a sucrose solution placed in pure water. If the sucrose molecules diffuse through the membrane, you would observe a change in the concentration of sucrose in the surrounding water over time. To disprove diffusion, you could use a membrane that is impermeable to sucrose, demonstrating that no concentration change occurs in the surrounding solution. Measuring the concentration of sucrose in both compartments before and after a set period would provide clear evidence of diffusion or lack thereof.
Design an experiment based on the principles of diffusion and osmosis that the assistant could use to determine which of the falasks contains each of the four unknown solutions?
I'm doing the same AP Bio essay right now. 1. Place each solution in a separate dialysis bag. 2. Place each dialysis bag in a solute (water). 3. Observe the dialysis bag in the solute for a couple of days. 4. Record the results with a Benedict's test to determine the amount of sucrose in each solute. Whichever solution diffused the most into the solute is the .2 solution. Whichever diffused the least into the water is the .8 solution, etc.
What would happen to the weight of a dialysis bag filled with molasses placed in a beaker of water?
The water in the dialysis bag would diffuse out into the molasses solution. This is because there is a high concentration of water inside the dialysis bag and a a lower concentration of water in the molasses solution. By diffusion or osmosis, the water would tend to move from the concentrated bag to a less concentrated solution.
What will happen if you put a dialysis bag of water into a water becker?
If you place a dialysis bag filled with water into a beaker of water, there will be no significant change in the dialysis bag's contents, as both are isotonic. Since there is no concentration gradient for water to move across the semi-permeable membrane of the dialysis bag, osmosis will not occur. The bag will remain filled with water, and the surrounding water in the beaker will remain at the same level. However, if the dialysis bag contains solutes that are not present in the beaker, osmosis may occur, leading to a change in the bag's volume.
How peritoneal is formed?
peritoneal dialysis work on the same principle except abdomen has a peritoneal cavity, lined by a thin epithelium called as peritoneum. peritoneal cavity is filled with dialysis fluid that enters the body through a catheter. excess water and waste pass through the peritoneum into the dialysis fluid. this process is repeated several times in a day.
How can dialysis tubing be used to model a selectively permeable membrane?
Dialysis tubing can model a selectively permeable membrane by allowing certain small molecules and ions to pass through while restricting larger molecules. When filled with a solution and submerged in another solution, the tubing will permit the diffusion of substances like water, glucose, and ions based on concentration gradients. This setup effectively demonstrates principles of osmosis and diffusion, illustrating how cells selectively allow materials in and out. By observing changes in mass or concentration, one can visualize the behavior of a selectively permeable membrane in biological systems.
What is the residue left after charring a sucrose?
What is left after heating sucrose is charcoal or solid carbon (C2). Heating causes sucrose to decompose as referred to this chemical reaction: C12H22O11 + O2 (the air is filled with it) - Heated --> CO2 + H2O + C2
Why does stator water have to be distilled?
It's inpure otherwise Water that is not distilled is filled with diseases or other naughty bad things that we all know is a big no no to drink... Isn't that right bobo? *looks at the bear* Bobo: aaaarrgh

What is filled with eletrically charged ions?
A plasma may contain only electrically charged ions. A solution of an electrolyte in a solvent is also "filled with electrically charged ions" in the sense that such ions are present throughout the solution at the same density, but the solution also contains solvent and therefore is not filled with ions in the sense that nothing else is there.
Would it matter if droplets of distilled water were left in the burette when it was filled with sodium hydroxide?
Yes, it would matter because any residual water in the burette could potentially dilute the sodium hydroxide solution, leading to inaccurate measurements or titration results. It is important to ensure the burette is completely dry before filling it with the sodium hydroxide solution to avoid any potential errors.
