We did this experiment to prove the diffusion of different substances through dialysis tube. We used what we knew about diffusion to do anticipations on what we thought the mass of the dialysis tube to be after submersing them for 30 mins and we knew that diffuse occurs from highest concentration to lowest concentration.
Since the dialysis tubes are filled with different substances than what they are being put into so they should all addition or lose mass. If the dialysis tube is submerged in different substance than what is in the tube so some of the dialysis tubes will lose mass and some will derive mass.
To get down this experiment we filled 5 dialysis tubes with one of the five substances: H2O. egg white. NaCl. glucose. or sucrose. The equipment used was: 5 dialysis tube. a graduated table. bekers. H2O. egg white. saccharose. glucose. NaCl. and 5 cups. We put the five dialysis tube filled with one of the five substance into a cup filled with one of the substance: H2O. egg white. NaCl. glucose. or sucrose. Then we let them sit in there for 30 mins so took them out of the cups and remassed them.
The dialysis tubing did allow some of the different solutions in but non all of them. Most of the dialysis tube gained mass and some lost some mass every bit good. We found that the substances go from an country of high concentration to an country of low concentration. The information supports our intent of making this experiment to happen out what happens when a substance in a dialysis tube is put into a cup of a difference substance to see which 1s gain mass and which 1s lose mass. A form of the information is that the control group did non derive or lose mass. Two of the substances gained mass and two of the substance lost mass. Our consequences proved our hypothesis that some of the dialysis tubes would derive mass and some of the dialysis tubing would lose mass. Because two of the dialysis tubes gained mass and two of the dialysis tubes lose mass it merely shows that the substances went for an country of high concentration to an country of low concentration.
A few mistakes of our experiment is that we could hold non used sufficiency of the substances in the dialysis tubes or we could hold left the dialysis tubings the cups of substance for a long sum of clip which could hold changed our consequences majorly because the more clip the dialysis tubes sit in the cup of substances the more they had clip to spread.
Osmosis through Dialysis Tubes
We performed this experiment to see how H2O moves across a semi-permeable membrane. We filled the dialysis tubes with different Mole concentrations of saccharose. and we used our cognition of osmosis to calculate out the different concentrations. If the dialysis tubing increases both in size and weight. so that dialysis tubing had the highest mole concentration of saccharose.
We learned that during osmosis. a signifier of inactive diffusion which means that it requires no energy to travel across the membrane. H2O will ever travel to the country where the H2O concentration is lower. so if the saccharose has a high mole concentration so the H2O will travel into the bag since there is less H2O at that place. and if the bag has a low mole concentration so there will be small H2O traveling into the bag since there is already a comparatively high concentration in the bag.
The stuffs we used to carry on this experiment were: 6 Dialysis Tubes. 6 different mole concentrations of saccharose ( 0 M concentration. 2 ten 10??M concentration. 4 ten 10?? M concentration. 6 ten 10?? M concentration. 8 ten 10?? M concentration. 1 M concentration ) . 6 cups to keep the H2O. a graduated table to weigh the mass of the dialysis tubing before submersing the bags in H2O and after.
To get down this experiment we foremost filled the bags with the different mole concentrations of saccharose. the different concentrations were color-coordinated with different colourss for a different concentration. Next we weighed the mass of the bags before submersing them in the H2O. and filled the cups with H2O so that we could submerse the tubings. After the bags were massed and the cups were filled with H2O we submerged the bags for 30 proceedingss. After the 30 proceedingss were up we took the bags out of the H2O and blotted them off with a dry paper towel. Finally we massed the bags and recorded our consequences so that we could compare them with the consequences from before we submerged the tubings.
After analysing our consequences we concluded that the Blue substance was H2O. because it gained no mass.
The violet substance was the 2 x 10?? M concentration because it gained small mass. more than the bluish substance.
The visible radiation green substance the 4 x 10?? M concentration because it gained some mass. more than the 2 ten 10?? . concentration but non every bit much as the 6 x 10?? M concentration.
The ruddy substance was the 6 x 10?? M concentration because it gained more mass than the 4 x 10?? M concentration but less than the 8 x 10?? M concentration.
The green substance was the 8 x 10?? M concentration because it gained more mass than the. 6 Molar concentration but less than the 1 M concentration. and eventually the Yellow substance was the 1 M concentration. because it gained the most mass.
Our consequences answered our inquiry. How can you state the molar concentration of a 0. 2. . 4. . 6. . 8. and 1 molar concentration of saccharose? Our consequences showed us that our hypothesis. If the dialysis tubing increases both in size and weight. so that dialysis tubing had the highest mole concentration of saccharose. was besides right because the Yellow substance gained the most aggregate out of all the other substances and was besides the substance with the highest Molar concentration of 1. and the Blue concentration gained no mass therefore it was H2O. because if there is every bit much H2O on the interior as the outside so no osmosis takes topographic point.
Some beginnings of mistake for this experiment is that we could hold left the solutions in thirster. perchance altering our consequences. Or that we could hold besides non used sufficiency of the solutions.
Diffusion utilizing Potato unit of ammunitions
We are carry oning this experiment in order to see what happens during the procedure known as diffusion across a semi-permeable membrane. Our hypothesis was that if the Molar concentration is higher in a sucrose solution so the murphy will lose mass and if the Molar concentration is lower in a sucrose solution so the murphy will derive mass.
We learned about diffusion and how a semi-permeable membrane merely lets certain molecules pass through it. Diffusion is the act of a molecule passively go throughing through a semi-permeable membrane. This action of diffusion helps modulate the cell’s processes and this is done on a regular footing so that the cell can populate and map.
For this experiment we needed: 36 murphy sticks ( 18 of a sweet murphy and 18 of a regular murphy ) . 6 sucrose solutions ( 0M. . 2M. . 4M. . 6M. . 8M. and 1M ) . a graduated table. cups. First what we did was we massed our murphy sticks. and recorded them. Next we filled the cups with the different solutions of saccharose and submerged the murphy sticks for 30 proceedingss. After the 30 proceedingss we massed the murphy sticks and recorded the alterations and analyzed the old informations with the information we received. here are our consequences:
After analysing our consequences. we concluded that the murphy sticks in the Blue concentration gained the most aggregate out of all the solutions. and the xanthous concentration grained non mass. but alternatively lost mass. This is because H2O will travel from an country of high concentration to an country of low concentration. We besides calculated the H2O potency of the murphy sticks and found it to be -7. 86 for a regular murphy and -17. 01 for the sweet murphy.
All of the experiments that we did. the substances had a semi-permeable membrane that merely allow certain things through it. All of the experiments consisted of seting different substances into cups filled with different solution and seeing if they lost or gained mass dependant on if the sum of H2O that was in the substances and the solutions. There was a form throughout all of the experiments where one of the substances in the cups of solution gained nor lost mass but stayed the same and two of the substances in the cups of solution gained mass and two of the substances in the cups of solution lost mass.
