Osmosis is often defined as the flow of water through a semipermeable membrane, from a dilute solution to a more concentrated solution. Video experiment #1 – saturated sucrose/dialysis tubing/water osmosis from U Mich. https://youtu.be/pCupvFGN4bw A saturated solution of sucrose-containing a red dye is separated from water by dialysis material. What happens to the volume of sucrose solution during the experiment? How do you know that the sucrose solution did not flow into the beaker of water? (Give evidence from your observation of the experiment.)

Can sucrose pass freely through the membrane of a dialysis tube? Explain. (Biochem)
Describe the similarities and differences between the dialysis bag and a cell membrane. Be specific. If you want water to flow out of a dialysis bag filled with a 50 percent sucrose solution what would be the minimum concentration of the beaker solution need to be?
Can sucrose pass freely through the membrane of a dialysis tube? Explain using examples. (Biochemistry)
A dialysis tube is constructed of a cellophane-like material. The molecular structure of the material forms a membrane containing numerous small-diameter pores. The dialysis tube containing a 10% protein solution and 10% amino acid solution was placed into a beaker containing water. After 10 minutes the water in the beaker tested positive for amino acids but negative for protein. Why were amino acids but not protein able to pass through the dialysis membrane? Water molecules blocked the pores so that the protein was unable to pass through the membrane. Amino acids, but not proteins, are small enough to pass through the pores in the tube's membrane. Protein is too hydrophobic to pass through the pores in the membrane. Amino acids blocked the pores so that the protein was unable to pass through the membrane.

Inside a beaker, dialysis membrane A is filled with a 50% glucose solution and dialysis membrane B is filled with a 50% NaCl solution. Both bags are put into beakers containing 100% water. Which of the following choices is correct? (hint: the dialysis membrane is only permeable to water) a) For both solutions, it is isosmotic, and hypotonic so water flows into the membrane.b) For both solutions, it is isosmotic, and isotonic so there is not net flow of waterc) For both solutions, it is hyposmotic, and hypotonic so water flows into the membraned) For both solutions, it is hyperosmotic, and hypertonic so water flows into the membranee) For both solutions, it is hyposmotic, and hypertonic so water flows out of the membrane
Dialysis is a process of selective diffusion through a membrane. It is usually used to separate low-molecular-weight solutes which diffuse through the membrane from the colloidal and high-molecular-weight solutes which do not. What are the factors affecting dialysis.
A student designed an experiment to test whether different concentration gradients affect the rate of diffusion through dialysis tubing. Four different solutions (0% NaCl, 1% NaCl, 5% NaCl, and 10% NaCl) were tested under identical conditions. Twenty mL of each solution was placed into separate dialysis tubing that is permeable to Na+, Cl-, and water. Each bag was placed in a separate beaker and covered with distilled water. The concentration of NaCl in the water outside of each bag was measured at 40-second intervals. The graph below shows the results from the 5% bag: Concentration of NaCl Outside of Dialysis Bags Concentration of NaCl (mg/L) 400 320 240 160 80 0 40 80 Time(seconds) 120 5% Solution 160 a. Describe the process of diffusion through the dialysis tubing. b. If you were to design a different experiment testing rates of diffusion, identify experimental procedures. c. Analyze that data in the graph and describe the results. Provide reasoning to justify your answer. d.…

A dialysis bag contains 10% starch solution. The dialysis bag is placed in a beaker filled with deionized water. Ten drops of Starch indicator (iodine solution, KI) solution is placed into the deionized water. The water turns a yellowish-brown color, however, you notice that the starch solution begins to turn black. Describe what is happening with respect to the diffusion of starch.

For the following scenario you must draw the situation depicted, indicate which solution is hypertonic, hypotonic or isotonic (as applicable), and then show with arrows which way water will move. Then you must write your response in complete sentences, thoroughly explaining and justifying your arrows. a. Ouch! Sore throat! It is so swollen that it is sore and it is difficult to swallow. And you have an oral presentation today. Better gargle with salt water to reduce the swelling! Explain why this age old technique really works, by using the concept of osmosis.
