The above table represents the final and initial colors of the solution that was inside of the dialysis tubing and the solution that was in the beaker. A 15% glucose and 1% starch solution was placed inside of the dialysis tubing. The initial color of the solution in the bag was a cloudy white but after 30 minutes of sitting in the beaker of water and IKI the color turned a very dark purple almost black. Inside of the beaker was a water and IKI solution. After sitting for 30minutes this solution stayed the same color.

This table shows the colors of the solutions before sitting for 30minutes in the solution of water and IKI and the final color after the Benedict’s test has been performed on the solution. The initial color of the 15% glucose and the 1% starch before sitting in the beaker solution for 30 minutes and before the Benedict’s test was perform was a cloudy white color. After the Benedict’s test was performed on this solution it turned an orange color. The solution in the beaker which was distilled water was clear before the IKI was added and before the dialysis tubing was placed in it. After the Benedict’s test the solution turned blue.
