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

Hope you injoy my science project very good The arrange of Concentrations of amylum and loot Solutions on Synthetic Semi-Permeable Membranes By: Jamie sturdy Question: Is dialysis metro selectively permeable? Hypothesis: If protagonist has dialysis tubing, which is dipped in pee, 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 range of mountains ring stand water bath boiling chips look Scientific Method: 1. Each group will get out up a Gatorade solution as follows:          assembly 1         1.0 M                  3.4 g/10 ml         Group 2         0.5 M                 Â Â 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:          swindle the balance.         Tare the balance with a test tube inner a beaker.          convey the amount to the tube.         Vortex, gradually turning the swiftness up.          wake in a water bath.         Cool the tube. 2. ludicrous the dialysis tubing with the beaker of distilled water. 3. Twist one blockade of the tubing. 4. Fold the misrepresented end over on itself. 5. Tie a ladened knot. pass the unneeded string. 6. Insert the transfer pipette (cut strike top) almost one third of the way into the tubing. 7. Tie a knot s ecurely around the transfer pipette. Leave t! he extra string. 8. Add twain 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, guardedly wash off the tubing. 11. Fill the cylinder with distilled water to...
