Lab Report On Dialysis Tubing

There will be four or five groups, and each group will be given a concentration of glucose ranging from 5%, 10%, 20%, and 40%. 6 dialysis tubes will be given that will be used to simulate a cell's membrane as well as 6 beakers that will be filled to 200 ml with distilled water. The 4 different percentages of glucose, the control which is distilled water, and an unknown substance will all be inserted into the dialysis tubing. Before inserting the substances, one must take the dialysis tubing and clamp one end of the tubing. A graduated cylinder will be used in order to fill the 6 dialysis tubings with 10 ml of the given substances accurately. Next, once the substances have been put into the tubes, with two finger, smooth the end of the tubing sso to release the excess air. Once that is done, proceed to clamp the other side encasing the solution. Make sure no leaks are present. Next, the team will proceed by placing each distinct dialysis tubing into the 6 beakers with distilled water before. Make sure the beakers and everything is labeled accordingly so no confusion is possible, as so: beaker 1 = 200 ml dH2O + dialysis tubing with
Where by osmosis and the distilled water being hypotonic in nature, led for the free water to go into the tubing attempting to reach equilibrium. While, the lowest of free water concentration would be at the beginning where only glucose is basically present inside the tubing. Where as for the distilled water in the beaker, the obvious answer is at the beginning of the experiment where the water was pure in nature and hypotonic. While the lowest concentration of free water would be at the end of the experiment where the glucose mixed with the distilled water; reducing the amount of free water concentration. One can also see that all the water did not move through to the tubing as the there would have been no water left in the
