Jacob Rietschy Wed 9 am BENEDICT’S TEST FOR REDUCING SUGARS Purpose: In order to determine if different sugars are reducing sugars, Benedict’s reagent will be added to test for a redox reaction. Scientific Hypothesis: Sugars that are reducing will change color when Benedict’s reagent is added and is heated, while non-reducing sugars will not change color. Null Hypothesis: Reducing sugars will act no differently than non-reducing sugars when Benedict’s reagent is added. Predictions: If Benedict’s reagent is added to a reducing sugar and heated then the solution will change color. If Benedict’s reagent is added to a non-reducing sugar and heated then the solution will not change color. Rationales: Reducing sugars undergo a redox reaction with Benedict’s reagent, which adds oxygen to the sugar, changing its color. Therefore, if the sugar changes color when Benedict’s reagent is added then it is a reducing sugar. Reducing sugars undergo a redox reaction with Benedict’s reagent, which adds oxygen to
