identical in that they both contain a plastic zip-lock bag with a starch solution inside. The zip-lock bag is in a clear solution. What the students don’t know is that while the solution in one beaker is just water, the second beaker contains iodine. In beaker two, the colour of the starch inside the zip-lock bag will change. Students
Would the starch diffuse through the dialysis bag or would the starch. Or would both. Hypothesis:If diffusion occurs during the experiment then there will be glucose in the water of the cup because of diffusion from a high to a low concentration.
According to the standard curve of TPs detected at 292 nm, y = 14.315x − 0.0077, R 2 = 0.9992, the concentration of TPs in the supernatant was calculated. After centrifugation of the mixture of starch and TPs, the concentration of TPs in the supernatant was determined. at beaker glass. Volume of glycerol was 0,2 ml/gram from formulation of starch-chitosan. Water bath was heated and controlled the temperature that would be used ( T = 80 oC, 85 oC and 90 oC ). Beaker glass 500 ml filled with starch was put in the water bath then motor stirrer was switched on. Chitosan solution was added inside then The difference between molecules of high concentration and low concentration is called a concentration gradient. When a concentration gradient exists, diffusion will take place and molecules will move until equilibrium of molecules exists across the gradient. Osmosis is a process by which water moves through a selectively permeable membrane. Phoenix miner setupThe reason why I think that the water will diffuse through the bag because the concentration gradient outside the bag is more than inside the bag. MATERIALS: Dialysis Bag Starch Solution (Small Beaker) Strings (2) Iodine Beaker PROCEDURE: 1.Get starch solution and put it in the dialysis bag. 2.Tie both sides of the dialysis of the dialysis bag. The direction in which water molecules move during osmosis depends on where the water molecules are more highly concentrated. Study the diagrams below. Decide whether the solution in each beaker is hypotonic, isotonic, or hypertonic in relation to the solution inside the cellulose bag, then write your answer below each beaker.

(B) The pores of the bag are larger than the glucose molecules but smaller than the starch molecules (C) The bag is not selectively permeable. (D) A net movement of water into the beaker has occurred. (E) The molarity of the solution in the bag and the molarity of the solution in the surrounding beaker are the same. (1999 # 114) 9.
a The solution in the beaker is more concentrated with solute than the water in the bag. The water concentration (potential) is higher in the bag than the surrounding water, therefore the water must diffuse out the bag through the partially permeable membrane. Iodine molecules are small enough to pass freely through the membrane, however starch molecules are complex and too large to pass through the membrane. Initially there was a higher concentration of iodine outside than inside the tube. Thus iodine diffused into the tube with the starch. This turned the starch a darker colour. The concentration of starch in vines is related to their point of cold hardiness. The study shows that the concentration of starch in balcanica varieties is lower than in gallica varieties.

The effect of solute concentration. Pure water at atmospheric pressure has a solute potential of zero. As solute is added, the value for solute potential becomes more negative. This causes water potential to decrease also. In sum, as solute is added, the water potential of a solution drops, and water will tend to move into the solution.
The solution in the bag is hypotonic (lower solute concentration) to the solution in the beaker. The solution in the beaker is hypertonic (higher solute concentration) to the one in the bag. Water will move from the hypotonic solution into the hypertonic solution. In this illustration the two solutions are equal in their solute concentrations. Best blacktail deer rifleThere was no immediate effects, but 24 hours later we checked the bag and we found that the iodine entered the dialysis bag and the glucose exited the bag. The starch was too large to leave the bag but not the glucose. So the iodine and the glucose switched places till they were evenly distributed inside and out of the bag. .
