Iodine Test Lab Report

The experiment was conducted in order to discover the type of carbohydrate that made up the known and unknown solutions presented in the lab. After heating the monosaccharide solution containing the Benedict’s test, the change of color from blue to orange proved that monosaccharides showed a positive reaction to the test. When an Iodine test was conducted on the monosaccharide solution, the carbohydrate resulted in no color change from its original yellow/brown color, showing a negative reaction. In both the Iodine and Benedict’s test, a disaccharide solution tested negatively due to the fact that there was no color change in either test. A polysaccharide solution displayed a negative reaction to the Benedict’s test, but the solution portrayed a positive result to the Iodine test due to a color change to black. So, from this data collected, we can gather that in order to contain monosaccharides, the …show more content…
The honey solution displayed a positive result to the Benedict’s test and a negative to the Iodine test. When experimented with the Benedict’s test, the oat solution had a negative reaction whereas the Iodine test concluded with a positive reaction. The table sugar solution had a result of negative to both the Iodine and Benedict’s tests. The Benedict’s test on the apple juice solution produced a positive reaction but a negative one to Iodine. Finally, the powdered sugar solution displayed a negative reaction to both Iodine and Benedict’s test. By utilizing data table one, you know how the types of carbohydrates reacted to both the tests. With that information in mind, by translating those results to the outcome from data table two, you can conclude that the honey and apple juice solutions were made up of monosaccharides, the table sugar and powdered sugar solutions contained disaccharides, and the oat solution was composed of
