lab report for the diffusion lab

Questions: 

Q1:how would you explain the results you optioned? which substance(s) are entering the bag and which are leaving the bag?  support your answer with experimental evidence.

A1:the subtance entering the bah is iidim because the solution on the inside changed colors. witch turned the water clear. the glucose exited the bag because the water tested positive with the glucose test stripe

Q2:what evidence could have been collected to show quantitatively that water diffused tin no the dialysis bag?

A2:the bag had little tiny holes that water could get in here and resolve th molecules in the bag and beaker.

Q3:what result would you expcet if the experiment started with a glucose and IKI solution inside the bag and only starch and water outside?WHY? 

A3:i don't now what would happen  i think the results would be opposite then what we seen before.

Procedure:

1. fill a 8-oz cup two-thireds full with distilled water. add approximately 4 ml of IKI to the distilled water, mix well  and record the color of the solution in table 1.1. test this solution with a clucose indicator strip and record the results in table 1.1. 
2. test the 15% glucose/1% starch solution with a glucose indicator strip. record the resutlts in table1.1.
3. obtain a 30-cm piece of 2.5-cm dialysis tubing that has been soaking in water. tie off one end of the tubing to form a bag. to open the other end to the bag, rub the end between your fingers until the edges separate.
4.using a small funnel, place 15ml of the 15% glucose/1% starch solution in the bag. tie off the other end of the bag, leaving about 4 cm between the solution and the end of the bag so the contents of the bag can expand. record to color of the solution tin table 1.1.
