When orange iodine is exposed to starch it turns blue-black. in an experiment, you placed a cornstarch solution in a small plastic bag. next, you placed the the bag in a beaker of water containing 10 drops of iodine. if the solution in the plastic bag turned blue-black (check all that apply)?

The plastic bag was permeable to iodine.

The iodine moved into the plastic bag.

The plastic bag was selectively permeable.

Explanation:

Hello,

In this case, the available options are:

The plastic bag was permeable to cornstarch.

The plastic bag was permeable to iodine.

The iodine moved into the plastic bag.

The cornstarch moved into the beaker.

The plastic bag was selectively permeable.

Now, this a case in which the osmosis process is carried out, it is understood as "the spontaneous net movement of solvent molecules through a selectively permeable membrane into a region of higher solute concentration, in the direction that tends to equalize the solute concentrations on the two sides". In such a way, we verify that among the options, the following apply:

The plastic bag was permeable to iodine as it allowed its movement.

The iodine moved into the plastic bag as the solution in the plastic bag turned blue-black.

The plastic bag was selectively permeable as it allowed the movement of iodine.

Best regards.
