a chemist performed an experiment to check the percebtage purity of a sample of glucose

We use chemical reagents in food tests to identify the presence of biological molecule.Identify the correct colour change you would expect, when a substance tests positively for the presence of glucose after Benedict's solution is added.Blue to purpleOrange-brown to blue-blackClear to cloudy emulsionBlue to brick redI DON'T KNOWSUBMIT ANSWER

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

If the concentration of glucose  (C6H12O6)  in the blood is 0.9 g L-1, then the molarity of glucose in the blood is 1. 5 M2. 50 M3. 0.005 M4. 0.05 M
