Virtuаl Lаbs - Test fоr Sugаrs Hоw dо you activate the Benedict test? Prepare the Sample: Place the liquid sample (e.g., glucose solution, fruit juice, etc.) into a test tube. If the sample is solid, dissolve it in water. Add Benedict's Reagent: Add an equal volume of Benedict's reagent to the sample in the test tube. The solution will initially appear blue. Heat the Mixture: Place the test tube in a boiling water bath (around 95-100°C) for about 2-5 minutes. The heat will cause the reaction to occur. Observe the Color Change: After heating, observe the color change in the solution. A positive result, indicating the presence of reducing sugars, will show a color change from blue to green, yellow, orange, or red, depending on the concentration of reducing sugars.
