Fehling’s solution, or Fehling’s reagent, is a chemical reagent that is used to distinguish between an aldehyde and a ketone other than α-hydroxy ketone. Practically, it is used for the determination of reducing and non-reducing sugars that are present in carbohydrates.
9 Απρ 2021 · What Is Fehling’s Test? The Fehling’s test was developed by German chemist Hermann von Fehling in 1849. It is generally a test for reducing sugars and non-reducing sugars; and also a supplementary to the Tollens’ reagent test.
Fehling’s test developed by German chemist H.C. Von Fehling is a test used to differentiate between ketone functional groups and water-soluble carbohydrates. Learn more about the preparation, procedure, reaction and uses here.
22 Απρ 2024 · It is called Fehling’s test or Fehling’s reaction. The chemical principle of this test is based on the reaction of oxidation of the copper and the power-reducing sugars (monosaccharides, polysaccharides, aldehydes and some ketones).
Fehling’s solution is an alkaline solution containing copper (II) ions which act as the oxidising agent. When warmed with an aldehyde, the aldehyde is oxidised to a carboxylic acid and the Cu 2+ ions are reduced to Cu + ions.
27 Απρ 2018 · Fehling’s test is one of the sensitive test for detection of reducing sugars. Fehling’s reagents comprises of two solution Fehling’s solution A and solution B. Fehling’s solution A is aqueous copper sulphate and Fehling’s solution B is alkaline sodium potassium tartarate ( Rochelle salt).
14 Νοε 2019 · The Fehling test was developed in 1848 by Herrmann Fehling. Like Benedict’s test, it is also a sensitive test for the detection of reducing sugars. Fehling’s reagents comprise of two solutions; Fehling’s solution A (which is an aqueous copper sulphate) and solution B (which is an alkaline sodium potassium tartarate or Rochelle salt).
