WebMonosaccharides. In organic chemistry, Fehling's solution is a chemical reagent used to differentiate between water-soluble carbohydrate and ketone ( >C=O) functional groups, and as a test for reducing sugars and non-reducing sugars, supplementary to the Tollens' reagent test. The test was developed by German chemist Hermann von Fehling in 1849. WebWhich of the following statements is true about Benedict's and Fehling's tests?* Please choose one correct answer only. A.

Uji fehling dilakukan dengan cara menambahkan pereaksi fehling yang terdiri dari fehling A yaitu larutan CuSO 4 dan fehling B yang terdiri dari K-Na-tartrat dan NaOH ke dalam larutan, kemudian dipanaskan sambil digoyang. Pada uji iod, l mL larutan amilum ditambahkan dengan 5 tetes larutan iodin. Konstruksi MFC WebFehling's, Benedict's, and Tollen's test can all be used as an analytical test for reducing sugars. The Fehlings and Benedict are a blue Cu(II) solutions that turns precipitate a red color in the presence of an Aldehyde (reducing sugars like aldose). Fehlings requires heat to complete the reaction. Tollens uses silver (diamminesilver ion).
WebAdd 2 ml of Fehling’s solution A and Fehling’s solution B to it. Keep the solution in a boiling water bath for about 10 minutes. If there is the formation of red precipitate then the presence of carbohydrate is confirmed. (c) Benedict’s Test: Take the given sample solution to be tested in a clean test tube.
