Dialysis Tubing Experiment
1. The hypothesis if water is added to the cup then the mass and volume will decrease because water will go into the tubing to decrease solute concentration was supported by the data found in Table 1 and 2 because the cup holding the dialysis tubing with the protein solution’s mass decreased by 7.61 grams and the volume decreased by 17.3 milliliters while the mass of the cup with the tubing holding glucose solution also decreased by 1.19 grams and the volume decreased by 2.2 milliliters (Emma Ricks and Allen Hansen). The movement of water into the protein solution bag caused the mass to increase by 7.95 grams and the volume to increase by 2.4 milliliters and the glucose solution bag increased by 1.97 grams in mass and 2.2 milliliters in volume (Emma Ricks and Allen Hansen). The water had a net flow of moving from high concentration outside of the tubing to a low concentration moving into the bag to lessen the concentration of the different solutes. …show more content…
The water in the cup tested negative for protein showing that nothing diffused out of the tubing, water only diffused in. There was no net flow for the protein as it could not get through the membrane into the

    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.…

    Watch the Cell Transport video to see an actual dialysis experiment performed. Then click Simple Diffusion. The opening screen will appear in a few seconds (Figure 1.1). The primary fea- tures on the screen when the program starts are a pair of glass beakers perched atop a solutions dispenser, a dialysis mem- branes cabinet at the right side of the screen, and a data col- lection unit at the bottom of the display. The beakers are joined by a membrane holder, which can…

    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 one places a 1.0 M solution of glucose inside a bag and then places that bag into a beaker containing a 1.0 M solution of sucrose, the percent of mass lost in the bag is 10.5%. The solution in the bag is hypertonic while the solution in the beaker is hypertonic, which is why water moves from the bag to the beaker and the bag loses mass.…

    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…

    Seal the end if it is not already closed. Next, pick up a pipette and fill it with glucose. (Use this pipette only for glucose) then release the glucose into the dialysis tubing. Place four more pipettes full of glucose into the dialysis tubing. Now it is time to get another pipette (not the one used for glucose) and fill it with starch and release it into the dialysis tubing. Repeat this 4 (four) more times until there is a total of 5 pipettes of glucose and 5 pipettes of starch in the dialysis tubing. Mix the solution. Next, seal the dialysis tubing completely and make sure there is little to no air left in the dialysis tubing. Rise the bag with water. Next, fill a 400ml beaker with 300ml of water. Add 5 pipettes of Lugol´s into the 300ml of water. Mix the solution gently. Place the dialysis tubing bag into the 400ml beaker and leave for 30 minutes. After 30 minutes remove the bag and record your findings. Get 3 test tubes and label them “control” “bag” and “beaker” Next fill an unused pipette with water and pour it into the control test tube. Open the dialysis tubing and fill a pipette of the solution inside using an unused pipette. Repeat again and pour into the bag test tube. Place two pipettes of the beaker solution into the beaker tube. Add one pipettes of Benedict´s into each tube Heat all tubes for three minutes. Record…

    4. The glucose molecules were able to diffuse from the right beaker to the left beaker until equilibrium was reached, allowing both sides of the beaker to contain the same concentration of glucose. The albumin was not able to diffuse through the 200 MWCO membrane because it was too large thus resulting in osmotic pressure within the left side of the beaker.…

    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.…

    We started setting up our experiment by measuring different molar solutions (0M, 0.25M, 0.5M, 0.75M and 1M) of sugar and putting them into separate bottles, along with one bag (12g) of yeast and 300ml of water. We then attached a tube going from the top of each bottle to separate test tubes which were entirely full of water and were placed upside down in a tub of water, stopping the tube from emptying and…
