Movement/decomposition of IKI

Submitted by Susan Gingold (guest) on Wed, 10/26/2016 - 3:37pm.

When the bag of starch solution is placed in the beaker of water/IKI, we are wondering if:
1) the IKI moves in AND out of the bag?
2) the water moves in AND out of the bag?
2) if the beaker is left out for several hours (or overnight), the bag becomes very dark whereas the solution in the beaker becomes clear. Is this because all the IKI diffuses in or because of photo-decomposition?

Thank you
