Diffusion and OsmosisLab Report on Diffusion and Osmosis Our goal is to represent diffusion and osmosis. Diffusion is the process by which particles of liquids, gases or solids mix as a result of spontaneous movement caused by thermal agitation and dissolved substances move from a region of higher concentration to one of lower concentration. Osmosis is a process of absorption or diffusion suggestive of the flow of osmotic action. In our laboratory experiment, we performed a procedure to observe osmosis along a free energy gradient. He had to determine whether the experiment was hypotonic, hypertonic, or isotonic. Our second experiment was to observe diffusion across a differentially permeable membrane. It is used to understand the movement and reaction of sodium hydroxide and phenolphthalein across a permeable membrane. Furthermore, we also calculate the movements and reaction of iodine and starch in a different container. In our experiment to observe osmosis along a free energy gradient, we would have to collect all these supplies.* We would first get eight pieces of string and four pieces of dialysis. pre-soaked tube approximately fifteen cm long. Then we would seal one end tightly by folding and tying it.* We would leave one end open to fill with different percentages of sucrose.* In the first dialysis tube (bag A), we would place ten ml of 1% sucrose. In bag B we will also insert ten ml of 1% sucrose. Bag C would be different because it contains ten milliliters of twenty-five percent sucrose. Bag D has a sucrose percentage greater than 50% and 10 ml. We also label these bags by writing the letters AD and place them in the bag.* After the solution is sucrose, which is a disaccharide composed of glucose and fructose. If it is inserted, we will tie the ends.* We will then weigh the bag and record it on a graph before inserting it into the beaker containing the sucrose solution.* After weighing the dialysis bag and obtaining the initial weight, we place it
