Question
hich one of the following reagents is used to test for the presence of glucose (a reducing sugar)?Benedict’s reagentEthanol and waterBiuret reagentIodine solution
Solution
Benedict’s reagent is used to test for the presence of glucose (a reducing sugar). Here's the step-by-step process:
-
Add Benedict's reagent to the solution you are testing. Benedict's reagent is a blue solution.
-
Heat the mixture in a water bath. This is usually done at a temperature of about 80-85 degrees Celsius.
-
If glucose is present, the solution will change color. The color change can range from green to yellow to orange to brick red, depending on the amount of glucose present. The
