question 2

Essay

Four small bags are filled with a 10% starch solution.The membrane of each bag contains microscopic pores large enough to let smaller water molecules cross but too small for the larger starch molecules to cross.
Each bag is placed in a separate beaker as follows:
Bag 1 is placed in distilled water containing no starch (0% starch).
Bag 2 is placed in a solution of distilled water and 5% starch.
Bag 3 is placed in a solution of distilled water and 10% starch.
Bag 4 is placed in a solution of distilled water and 50% starch.
The bags are weighed initially and at regular intervals for a specific period of time.Some bags saw a change in weight, and some did not.
