The Process of Diffusion and Osmosis and the Ways in Which They are Affected by Various Factors Viewed by Using Dialysis Tubing and Several Solutions Composed of Different Molecules Abstract: Two lab experiments were done. ... The second experiment was to observe osmosis by filling 6 dialysis bags, 5 were filled with different amounts of sucrose and water and 1 was filled with just water. ... It was determined that, due to osmosis, the dialysis bags with the sucrose would increase in their mass each depending on the amount of sucrose it contains, and the bag full of water would have the same mass as it had initially. ... Osmosis is a special case of passive transport in which the diffusion of water molecules across a selectively permeable membrane takes place. ... Purpose: The purpose of this experiment was to conduct an investigation to demonstrate the processes of diffusion and osmosis and explain how diffusion is affected by many factors. ... Hypothesis (B): If 6 bags of dialysis tubing are filled, 5 of them with 15mL of different concentrations of sucrose and the same amount of water, and 1 of them with 50mL of water, then, due to osmosis, those bags with a higher concentration of sucrose will be greater in mass after placed in 200mL of water for 30 minutes when compared to their initial mass before placed in the water. ... When 6 bags of dialysis tubing were filled, 5 of them with 15mL of different concentrations of sucrose and the same amount of water, and 1 of them with 50mL of water, then, due to osmosis, those bags with a higher concentration of sucrose were greater in mass after placed in 200mL of water for 30 minutes when compared to their initial mass before placed in the water. ... This experiment was very significant in learning the processes of diffusion and osmosis. ... Osmosis can be related to the way in which a person’s body reacts to no muscular movement over long periods of time. ... This medicine works through osmosis. |
