How does the benedict's test work
WebIn turn the aldehyde is oxidized to the corresponding carboxylic acid. The electron-half-equation for the reduction of dichromate (VI) ions is: (3) C r 2 O 7 2 − + 14 H + + 6 e − → 2 C r 3 + + 7 H 2 O. Combining that with the half-equation for the oxidation of an aldehyde under acidic conditions: (4) R C H O + H 2 O → R C O O H + 2 H ... WebFructose is a ketose. ketones usually do not give a positive reaction with Benedict reagent. why is fructose oxidized by Benedicts reagent fructose will have RED ppt because it is a reducing sugar. reducing sugar will always give positive. Ketones is presence of basic Benedict reagent will become aldoses (glucose)

WebAs noted in the paper, 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 as the alkali component, to reduce the corrosiveness, and by substituting citrate for tartrate as the agent to chelate the Cu 2+, to make the reagent more stable. WebNov 2, 2016 · Benedict's reagent consists of sodium carbonate, sodium citrate ( N a X 2 ( C X 6 H X 6 O X 7) ), and copper (II) sulfate dissolved in water. It's pretty clear now, that the main difference between the two reagents is the complexing agent (citrate in Benedict's and tartrate in Fehling's).
