2. In the presence of monosaccharides IKI will be what color (Experiment #2)?
2 Starch Test following Acid catalyzed Hydrolysis and Oxidation with Benedicts of STARCH. An acidic solution of Starch, was heated for 1-2 hours. Each 15 minutes, a sample was removed, added to a chem plate and the IKI solution added. The solution was heated until the starch test became negative. At this point, the Sugar Test (Benedicts was repeated). Results are below:
These results are shown on the left-side chemplate. The results of the initial Benedict’s test with starch (left test tube) and after hydrolysis (right test tube) are shown above on the right.
