What substance in the dialysis tubing or jar did not diffuse across the dialysis bag membrane and why?
molecular weight higher than the pore size of the tubing or dialysis bag material doesnt go.
Does albumin diffuse through a dialysis tube?
can protein (albumin) diffuse out of a dialysis tube and why
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.
Which substances did not diffuse the membrane?
starch doesnt diffuse through the dialysis membrane.
Which solutes diffuse from patient's blood during dialysis?
urea
Would sugar's starch or salt diffuse faster in a dialysis bag?
When considering a dialysis bag, size will determine whether the molecules will permeate the bag. The smaller the molecules, the easier they well be able to pass through, and the faster diffusion will take place. Starch is a carbohydrate - a macromolecule formed from repeating bonded units of glucose monomers. Salt, in comparison, is simply Na+ and Cl- ions (in the aqueous solution). Starch will have a much tougher time getting through the artificial membrane, so it is a safe bet that salt will diffuse faster.
How is calcium chloride made for dialysis?
meh
A dialysis bag is filled with distilled water and then placed in a sucrose solution?
Distilled water will move out of the dialysis bag and into the sucrose solution due to osmosis and the fact that the dialysis bag has a hypertonic solution of H2O as compared to the sucrose solution.
Which substance did not diffused through the membrane?
starch doesnt diffuse through the dialysis membrane.
What is the highest concentrate ingredient in a dialysis solution?
sodium chloride
Why did osmosis, but not diffusion of sucrose molecules, occur across the dialysis membrane containing 20% sucrose solution?
Sucrose cannot diffuse across a dialysis tubing. This is because it's size is too large to go through the tubing. Water can diffuse across.
What can be done to ensure the sugars and amino acids and certain amounts of salts are not remove from the blood by dialysis?
Keep the concentration of these substances in the dialysis fluid same as in the blood, and they won't diffuse out.
