What else can I help you with?
Will protein diffuse through dialysis tubing?
Yes, protein can diffuse through dialysis tubing due to its small size and ability to pass through the pores of the tubing.
Can oxygen pass through pores of dialysis tubing?
Yes, oxygen molecules are small enough to pass through the pores of dialysis tubing. This allows oxygen to diffuse into the dialysis tubing from a surrounding solution or environment.
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.
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.
State one characteristics property of the dialysis tubing and why is this property important?
One characteristic property of dialysis tubing is its semipermeability, allowing only certain molecules to pass through while blocking others based on their size. This property is important because it enables the separation of substances by preventing larger molecules from crossing the membrane while allowing smaller molecules to diffuse across, leading to purification and separation processes in dialysis.
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.
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.
Why urea passes through the dialysis tubing into the dialysis fluid?
Urea passes through the dialysis tubing into the dialysis fluid due to the process of diffusion, where molecules move from an area of higher concentration to an area of lower concentration. The dialysis tubing is semi-permeable, allowing small molecules like urea to cross while retaining larger molecules and cells. As urea accumulates in the blood and reaches a higher concentration than in the dialysis fluid, it diffuses out to achieve equilibrium. This process helps remove waste products from the blood in dialysis treatments.
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 sucrose molecules enter the dialysing tubing during dialysis?
NO
Can hydrogen ion pass through the pores of dialysis tubing?
No.Hydrogen ion cannot pass through the pores of dialysis tubing.
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.
