Dialysis Tube And Osmosis
The reason of this lab was to see if the size of the dialysis tube affects its mass. Based on the results of this experiment, the size of the dialysis pouch does not affect the mass, because the dialysis pouches all had the same reaction of gaining and then losing weight. The data shows that all the three trials went up in weight until six minutes. This was the peak weight the tubing could go. Then after that until twelve minutes in went down. My theory about this is that due to osmosis/diffusion, the molecules want to reach equilibrium. The weight gets too heavy due to the water and then goes down. This results in that in osmosis, the weight of the two solutions can change a lot (goes up and down constantly). One error I saw that impacted

    of dialysis tubing, 25 mL of sucrose solutions with concentrations of 0.02 Molar, 0.04M, 0.06M, 0.08M, 1.0M, as well as 25mL of distilled water, six 250 mL beakers, a balance, and paper towels. We first cut the dialysis tubing into 6 pieces, each 1ft. long, and placed them into a beaker of water. We then tied off the dialysis tubing and poured 25 mL of distilled water in. We repeated this with the rest of the five pieces dialysis tubing, pouring a different molarity of sucrose solution in different dialysis tubes. After all the tubes were filled and tied, we then dried the bags and weigh each one on the scale. After all the data was recorded, we filled all the beakers about ¾ full of distilled water, placed the bags into each beaker in unison, and waited 30 minutes. Next, the bags were removed from the beakers, dried, and weighed separately. We expected the mass to increase with increasing molarity because with the higher the concentrations, more water would need to be diffused into the bag to reach…

    If the four dialysis tubes containing different concentrations of sucrose are all placed in their appropriate solutions for 20 minutes, then my predictions are as follows: The 1% in 1% sugar solution will keep a constant weight and stay the same size. The 1% in 50% solution will shrink, due to the higher concentration of sugar outside of the bag. The 20% in 1% solution will swell, due to the higher concentration inside of the bag, and the 50% in 1% solution will do the same.…

    A way to relate this to the real world is that people could use the concept of osmosis to make more accurate administering IVs to put into patients in hospitals. Osmosis is extraordinarily important in the biological processes where the solvent is water. This transport of water and molecules across the membranes is essential to many processes in living organisms and keeping them healthy. In general, this experiment helped understand the different ways osmosis works and how concentration can change the weight of…

    Introduction: Osmosis is the diffusion of water from a higher concentration to a lower one through a semi-permeable membrane and occurs in the cells of organisms. It is affected by the addition of solute which would lower the water potential, making water potential and solute concentration inversely related. The concept of osmosis loosely described is that the presence of more solute outside the cell means the presence of less solvent (or water molecules in this case) and vice versa; the goal of osmosis is for the water molecules inside and outside of the cell to be equal, causing equilibrium and a stop to net water movement. The goal for a recent lab was to test whether cubes of potato would gain or lose weight depending on the amount of molar concentration of sucrose they soaked in. Solutions made of different molar concentrations of the solute sucrose were prepared before this lab. Potato cubes were weighed and recorded as the initial mass in the data. Four cubes of potato were placed into 100 mL of each solution and let stand overnight. The cubes were then taken out for the final total mass to be measured and recorded. In this experiment, the potato cubes were the dependent variables, and the molar concentrations were the independent or manipulated variables.…

    This makes sense because the farther the cell is from osmotic equilibrium, it will gain weight faster (McCutcheon 1926). This supported our prediction. The increase in osmotic rate because of an increase in solute concentration is because water moves from a solution of low solute concentration to a solution with high solute concentration. This means water rushes into a solute of higher concentration faster than a low concentration. This is why the artificial cell with 60% sucrose solution had the highest corrected cumulative change in weight and the fastest osmotic rate. The artificial cell containing water in 40% sucrose solution had a negative osmotic rate because water was leaving the cell and osmosis was occurring in the opposite direction. In this experiment, only one bag of water was placed in 40% sucrose solution. In other experiments, adding two more bags of water and placing them in 20% and 60% sucrose solutions could be tested to see if the rate of osmosis is similar to their 20% and 60% bag counterparts in water. Also, an experiment could be performed to show temperature is a factor in osmotic rates by having the same solute concentration in solutions and placing bags filled with water into them, each having a distinct…

    INTRODUCTION: In order to fully understand the concept of this experiment, one must first be introduced to diffusion. Diffusion is a spontaneous process by which molecule particles move from one area that is highly concentrated to another area in which its concentration is lower. Cells contain fluids and are surrounded by fluids; in order for a cell to function it is required to be in a balanced state. The progress in which a cell is in its balanced state is called equilibrium. Diffusion is a functioning way for cells to reach their equilibrium. Equilibrium is reached by controlling what enters and exits the cell through a cell membrane that selectively filters molecules by slowing down their movement, allowing them to pass through, or not allowing them to pass through the membrane. Diffusion and osmosis go hand-in-hand. Osmosis is generally the same as diffusion, however, deals solely with water. Osmotic pressure is the pressure of a solution against a semi-permeable membrane to prevent water from flowing into the membrane. In this lab, we are going to study tonicity; tonicity is the measure of this osmotic pressure and is the differential of pressure between two solutions separated by a selective membrane. To help identify the relative concentrations of solute particles of different solutions, we must understand that there are three possible differences in concentrations between a cell and its environment. The terms hypotonic, hypertonic, and isotonic are used in referring to the identification of the possible relative concentrations. The first term, hypotonic, is the solution that contains lower concentrations of solute particles, which means that the concentration inside the cell is greater than the concentration outside. A hypotonic solution causes the cell to swell in size. The second term, hypertonic, is the solution that contains higher concentration of solute…

    I’ve worked in renal dialysis at the Glens Falls Hospital for the past eight years. Working at the renal center is a very different type of nursing. You may say, “What is different about this type of nursing?” Well let me tell you, what is different about this type of nursing is that these patients require dialysis three times a week for the rest of their lives. In this type of nursing, it’s not like the patient who comes into the hospital needing surgery or possibly has an infection or pneumonia. These patients are usually in and out of the hospital in a week or two. Your contact with these patients is brief. In dialysis you take care of patients for years or until they die. It’s a very difficult situation because you get this great experience…
