Question

Your Turn In today's lab, you will make bags of dialysis tubing and fill them with a starch or glucose solution. You will submerge the filled bags in beakers of liquid. Note that all solution concentrations are expressed as percentages instead of molarities. Also note for all solutions that the solvent is water For each of the four bag/beaker setups you will do, list every molecule that will be able to pass through the tubing. Then, predict the direction of each molecule's net movement, if any. Tip: To determine net movement it might help to draw a picture of each bag/beaker setup to visualize any concentration gradients that might be present 1) List each molecule that can pass through the tubing Solution Liquid in dialysis bag in beaker 2) For EACH molecule you listed, predict its net movement: Into the tubing bag, out of the bag, or no net movement? 11 1% starch dH2O 21 20% glucose | dH2O 3140% glucose | dHO 4 | 10% glucose 10% glucose

Explanation / Answer

1) starch does not pass through dialysis tubing.

2)20% glucose: glucose will pass out of the dialysis tube. the movement will be from tube to beaker.

3) same as answer number two

4) no net movement because the concentration is the same in dialysis tube and water
