Answer 1

Benedict's solution is used in the laboratory experiments to detect the presence of reducing sugars or monosaccharides in a sample. Benedict reagent's colour change from blue to orange indicates that the test is positive confirms the presence of reducing sugars. One very important example of the use of Benedict's solution is in the diagnosis of Diabetes by detection of the presence of reducing sugars in a urine sample.
