The dialysis tube contained sucrose, NaCl, and starch and was placed in a beaker containing water and iodine. The bag started off clear then turned purple it also weighted 8.6 g at the beginning and 10 g at the end. Did water enter the dialysis tube?

Yes.
Explanation:
If you looked at the starting line the bag was in the tube it would be lower because water diffused across the membrane into the bag. The salt and glucose wher able to diffuse out which means the additional mass was water.
