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 ...

WebThe composition of fehling's reagent are : copper sulphate-CuSO4 [fehling A], sodium or potassium hydroxide-NAOH or KOH and Potassium sodium tartarate {KNa … 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 … See more Fehling's solution is prepared by combining two separate solutions: Fehling's A, which is a deep blue aqueous solution of copper(II) sulfate, and Fehling's B, which is a colorless solution of aqueous potassium sodium tartrate See more Fehling's solution can be used to distinguish aldehyde vs ketone functional groups. The compound to be tested is added to the Fehling's solution and the mixture is heated. Aldehydes are oxidized, giving a positive result, but ketones do not react, unless they … See more • "Fehling's Solution" . Collier's New Encyclopedia. 1921.
