After soaking dialysis tubing in water, it expands and becomes more pliable due to the absorption of water. This process allows the tubing to mimic the semipermeable nature of biological membranes, enabling it to effectively separate substances based on size when placed in a solution. The increased flexibility also facilitates easier handling during experiments or applications.

Why is dialysis tubing not submerged in pure water?

The tubing is permeable; itallows water to pass through the tube wall.


To Which substances was the dialysis tubing permeable?

I don't know unless you give more details!


Why does glucose diffuse through dialysis tubing into distilled water?

Glucose diffuses through dialysis tubing into the distilled water as, glucose molecules are small, it could fit through the pores of the dialysis tube. It is also because glucose is hydrophillic, (polar compound), which will dissolve in water as it is a polar compound as well.


Why would the water level increase in the capillary tube during the investigation because of osmosis?

The water level increases in the capillary tube due to osmosis because the concentrated sugar solution in the dialysis tubing creates a lower concentration of water molecules inside the tubing. This lower concentration of water inside the dialysis tubing creates a concentration gradient that drives water to move from the beaker outside the tubing into the tubing through osmosis, causing the water level in the capillary tube to rise.


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 physical property of the dialysis tubing might explain its differential permeability?

Dialysis tubing is an impermeable membrane/containment vessel that is stratified with microscopic holes which restrict certain molecules or particles from diffusing through them. This leads dialysis tubing to serve as a selectively permeable membrane because it selectively prevents certain molecules from crossing the membrane based on the size of the molecules. (Typically water and glucose will diffuse through, whereas starch and potassium iodide will not.


How can you tell if osmosis occurred in dialysis tubing?

Osmosis is usually detected by simply looking at the experiment - most of the time, enough water is transferred to cause a noticeable rise/fall in water levels. However, I assume you could tell through the usage of weighing scales - as water re-distributes, as would the weight.


What is the components of blood that cannot pass the dialysis tuning?

First of all, it is called Dialysis Tubing. Secondly, they are not 'Components', they are 'Contents'. Thirdly, only small molecules can pass through the semi-permeable membrane of the tubing, if using Diffusion. If using Osmosis, only water can pass through.


Do sodium ions pass easily through the pores of dialysis tubing?

Yes they do; this is because a sodium ion has a small [atomic] size compared to the size of the pores of the dialysis tubing. Then we can look at the our phospholipid bilayer; why there they are can pass easily? So if in the phospholipid bilayer they can pass easily through, so at the dialysis tubing they also can easily pass.


Can iodine pass through dialysis tubing?

As starch is something which the body wishes to hold onto, the nephrons in the kidney have small pores which stop larger particles like starch and also blood cells from escaping, while water and salts do. For this reason, the dialysis machine works in the same way.


Why can starch molecules not pass through dialysis tubing?

Starch molecules are too large to pass through the pores of dialysis tubing. Dialysis tubing has small pores that restrict the passage of large molecules like starch while allowing smaller molecules like water and ions to pass through via diffusion.


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.
