Benedict's solution

Ben·e·dict's solution

B0185700 (bĕn′ĭ-dĭkts)n. A solution of sodium citrate, sodium carbonate, and copper sulfate that changes from blue to yellow or red in the presence of reducing sugars, such as glucose. Also called Benedict's reagent.

[After Stanley Rossiter Benedict (1884-1936), American chemist.]

Benedict's solution

Benedict's reagent

n (Biochemistry) a chemical solution used to detect the presence of glucose and other reducing sugars. Medically, it is used to test the urine of diabetics[named after S. R. Benedict (1884–1936), US chemist]

Benedict's solution

Benedict's solution,

deep-blue alkaline solution used to test for the presence of the aldehydealdehyde
[alcohol + New Lat. dehydrogenatus=dehydrogenated], any of a class of organic compounds that contain the carbonyl group, , and in which the carbonyl group is bonded to at least one hydrogen; the general formula for an aldehyde is RCHO, where R is hydrogen

The substance to be tested is heated with Benedict's solution; formation of a brick-red precipitate indicates presence of the aldehyde group. Since simple sugars (e.g., glucose) give a positive test, the solution is used to test for the presence of glucose in urine, a symptom of diabetes. One liter of Benedict's solution contains 173 grams sodium citrate, 100 grams sodium carbonate, and 17.3 grams cupric sulfate pentahydrate. It reacts chemically like Fehling's solutionFehling's solution
, deep-blue, alkaline solution used to test for the presence of aldehydes (e.g., formaldehyde, HCHO) or other compounds that contain the aldehyde functional group, -CHO.
