Explanation / Answer

(Ans) Q.1 Cl and glucose will appear in the water outside the dialysis bag

(Ans) Q.2 Osmosis- the concentration of Cl and C6H12O6 was greater in the bag. The membrane was permeable to the size molecules of Cl and C6H12O6, therefore permitted the molecules to travel along the concentration gradient from a concentration of high to low

(Ans) Q.3 It was retained inside the bag as it was only a 1% solution. The concentration was much lower than that of the Cl and glucose
