what evidence did you observe to indicate that the starch was hydrolyzing while being heated?
After adding a significant amount of hydrochloric acid to the starch solution and heating the test tube for a while, the iodine proved that there was no longer any starch in the solution by staying a red/brown color in the solution.
Once enough sodium hydroxide was added to the starch solution, it became slightly basic, turning the litmus paper blue. The Fehling’s solution immediately became murky when the starch solution was added. As it was being heated, the solution became slightly green. Eventually, the murkiness cleared up a bit to a reddish blue solution with a bright red deposit on the bottom.
