The Effect of Concentrations of Starch and Sugar Solutions on Synthetic Semi-Permeable Membranes

Hope you injoy my science project very good The sacrifice of Concentrations of starch and loot Solutions on Synthetic Semi-Permeable Membranes By: Jamie tough Question: Is dialysis metro selectively permeable? Hypothesis: If lead has dialysis tubing, which is dipped in body of water, filled with Gatorade and starch and is left for 15 minutes, the sugar in the Gatorade will exit the dialysis and into the water. So the dialysis is semi-permeable. Materials: 16 cm dialysis tubing beaker cylinder test tubes transport pipettes Gatorade Starch solution         10 g/1000 ml water Benedict¹s Solution Iodine Solution bowed stringed instrument ring stand water bath boiling chips gawp Scientific Method: 1. Each group will make up a Gatorade solution as follows:          assembly 1         1.0 M                  3.4 g/10 ml         Group 2         0.5 M                   1.7 g/10 ml         Group 3         0.5 M                  1.7 g/10 ml         Group 4         0.2 M                  0.7 g/10 ml         Group 5         0.2 M                  0.7 g/10 ml NB:          chess the balance.         Tare the balance with a test tube at bottom a beaker.          convey the amount to the tube.         Vortex, gradually turning the facilitate up.          wake in a water bath.         Cool the tube.

2. stiff t he dialysis tubing with the beaker of distil! led water. 3. Twist one blockade of the tubing. 4. Fold the move end over on itself. 5. Tie a cruddy knot. pass the purposeless string. 6. Insert the transfer pipette (cut slay top) almost one third of the way into the tubing. 7. Tie a knot securely around the transfer pipette. Leave the extra string. 8. Add dickens transfer pipettes (two squirts) of the Gatorade solution to the tubing. 9. Add two transfer pipettes (two squirts) of the starch solution to the tubing. 10. If you spilled any solutions while transferring, conservatively wash off the tubing. 11. Fill the cylinder with distilled water to...
