Explanation:
Detailed explanation-1: -In lab, we used Benedict’s reagent to test for one particular reducing sugar: glucose. Benedict’s reagent starts out aqua-blue. As it is heated in the presence of reducing sugars, it turns yellow to orange. The “hotter” the final color of the reagent, the higher the concentration of reducing sugar.
Detailed explanation-2: -Benedict’s test for reducing sugars Place the tube in a water bath at about 95°C for a few minutes. Record the colour of the solution.
