Four small bags are filled with a 10% starch solution. The bag's membrane contains microscopic pores large enough to let smaller water molecules cross but not the larger starch molecules. Bag 1 is placed in a beaker of distilled water (0% starch). Bag 2 is placed in a beaker containing a 5% starch solution. Bag 3 is placed in a beaker of 10% starch solution and bag 4 is placed in a 50% starch solution beaker.

Bag 1: 10% starch / Beaker 1: 0% starch
Bag 2: 10% starch / Beaker 2: 5% starch
Bag 3: 10% starch / Beaker 3: 10% starch
Bag 4: 10% starch / Beaker 4: 50% starch

The bags are weighed initially and at regular intervals for a specific period of time. Some bags saw a change in weight, some did not. Answer the following questions based on the expected outcomes of this experiment.


Which bag should weigh approximately the same at the end of the experiment as it did at the beginning of the experiment?
◦ Bag 1
◦ Bag 2
◦ Bag 3
◦ Bag 4
