Barfoed's test is used to detect the presence of monosaccharide (reducing) sugars in solution. A test used to differentiate monosaccharide vs disaccharide. Barfoed's reagent, a mixture of acetic acid and copper sulphate, is combined with the test solution and boiled. A red copper(II) oxide precipitate is formed will indicates the presence of reducing sugar.
