Answer:
This experiment was conducted to investigate the selective permeability of dialysis tubing. The permeability of the tubing to glucose, starch and iodine (potassium iodide) was tested. The dialysis tubing was clipped to form a bag so that glucose and starch was fed into the bag through the other end, and was also clipped to avoid the seeping of the solution.

Answer:
Only Fehlings solution would react with the monosaccharides such as glucose, fructose, and galactose which of course, it will test positive with respect to the glucose.
Explanation:
Because Fehling's solution is mostly used as a sugar reduction test. This solution reacts with all reducing sugars that contain aldehydes or ketones. On boiling, the production of a brick-red precipitate indicates a positive test. Due to the presence of the C=O group in each component, consequently, all of these mono-saccharides will test positive for Fehling's solution.
