WebAn important reaction of monosaccharides is the oxidation of the aldehyde group, one of the most easily oxidized organic functional groups. Aldehyde oxidation can be accomplished with any mild oxidizing agent, such as Tollens’ reagent or Benedict’s reagent. With the latter, complexed copper(II) ions are reduced to copper(I) ions that form a ... WebDec 18, 2024 · Benedict’s goal was to improve this general method to make the reagent less corrosive and more stable. He accomplished this by substituting carbonate for hydroxide …

WebAug 29, 2024 · Benedict’s test can be performed by taking one millilitre of the analyte solution in a test tube and mixing it with two millilitres of Benedict’s reagent. Then, this mixture must be heated in a hot water bath for approximately 3 minutes (or until a visible change in colour occurs). How is Benedict’s solution prepared? Benedict's reagent (often called Benedict's qualitative solution or Benedict's solution) is a chemical reagent and complex mixture of sodium carbonate, sodium citrate, and copper(II) sulfate pentahydrate. It is often used in place of Fehling's solution to detect the presence of reducing sugars. The presence of other … See more Benedict's reagent is a deep-blue aqueous solution. Each litre contains: • 17.3g copper sulfate • 173g sodium citrate • 100g anhydrous sodium carbonate or, equivalently, 270g sodium carbonate decahydrate See more Benedict's quantitative reagent contains potassium thiocyanate and is used to quantitatively determine the concentration of reducing sugars. … See more The net reaction between an aldehyde (or an alpha-hydroxy-ketone) and the copper(II) ions in Benedict's solution may be written as: See more To test for the presence of monosaccharides and reducing disaccharide sugars in food, the food sample is dissolved in water and a small amount of … See more • Dextrose equivalent Other oxidizing reagents • Fehling's solution • Tollens' reagent See more slow cooker remove lid
