WebCopper(II) sulfate is a hydrated, blue solid – it is attached to water molecules. This becomes whitish when anhydrous – when it is not molecularly bound to water. When it is hydrated, there are usually five … WebWhich contain from (Copper, Sodium citrate, Sodium carbonate, Copper II sulfate pentahydrate). Principle : •The copper sulfate (CuSO4) present in Benedict's solution reacts with electrons from the aldehyde or ketone group of the reducing sugar in alkaline medium. •Reducing sugars are oxidized by the copper ion in solution to form a carboxylic

Preparing salts by neutralisation of oxides and carbonates

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 reducing … 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. This solution forms a copper thiocyanate precipitate … See more • Dextrose equivalent Other oxidizing reagents • Fehling's solution • Tollens' reagent Other reducing reagents • Jones reductor • Walden reductor 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 Benedict's reagent is added. During a water bath, which is usually 4–10 minutes, the … 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: RCHO + 2 Cu + 5 OH … See more WebCopper(II) sulfate is a skin and respiratory irritant and is moderately toxic by ingestion and inhalation.
