Dialysis experiment
This experiment was conducted to investigate the selective permeability of dialysis tubing. The permeability of the tubing to glucose, starch and iodine (potassium iodide) was tested. The dialysis tubing was clipped to form a bag so that glucose and starch was fed into the bag through the other end, … See more PURPOSE:The purpose of the experiment was to test the permeability of dialysis tubing to glucose, starch and iodine. Living cells need to obtain nutrients from their environment and get rid of waste materials to their surroundings. … See more Glucose, starch and iodine (potassium iodide) will readily pass through the membrane of the dialysis tubing. PREDICTION: The solution in the bag and the beaker will both … See more The solution in the bag turned blue-black in color owing to the movement of molecules of iodine from the beaker to the bag which contains starch. The solution in the beaker turned brown after Benedict’s test. This indicated … See more WebDialysis tubing is a semi-permeable membrane that is commonly used in biology and chemistry laboratories to separate small molecules from larger ones. It is made of a cellulose-based material that is specifically designed to allow small molecules, such as glucose and other sugars, to pass through while preventing larger molecules, such as ...
