- Benedicts_reagent abstract "Benedict's reagent (often sold as Benedict's Qualitative Solution or Benedict's Solution) is a chemical reagent named after an American chemist, Stanley Rossiter Benedict.Benedict's reagent is a chemical reagent commonly used to detect presence of reducing sugars, however other reducing substances also give a positive reaction. This includes all monosaccharides and many disaccharides, including lactose and maltose.Generally, Benedict's test will detect the presence of aldehydes, and alpha-hydroxy-ketones, including those that occur in certain ketoses. Thus, although the ketose fructose is not strictly a reducing sugar, it is an alpha-hydroxy-ketone, and gives a positive test because it is converted to the aldoses glucose and mannose by the base in the reagent.A positive test with Benedict's reagent is shown by a colour change from clear blue to a brick-red precipitate.One litre of Benedict's reagent can be prepared from 100 g of anhydrous sodium carbonate, 173 g of sodium citrate and 17.3 g of copper(II) sulfate pentahydrate. It is often used in place of Fehling's solution.The principle of Benedict's test is that when reducing sugars are heated in the presence of an alkali, they get converted to powerful reducing compounds known as enediols. Enediols reduce the cupric ions (Cu2+) present in the Benedict's reagent to cuprous ions (Cu+) which get precipitated as insoluble red copper(I) oxide(Cu2O).The color of the obtained precipitate gives an idea about the quantity of sugar present in the solution, hence the test is semi-quantitative. A greenish precipitate indicates about 0.5 g% concentration; yellow precipitate indicates 1 g% concentration; orange indicates 1.5 g% and red indicates 2 g% or higher concentration.".
