WebJun 11, 2024 · Fehling's solution consists of Fehlings A (copper (II) sulphate solution) and Fehling's B (alkaline 2,3-dihydroxybutanedioate (sodium tartrate) solution), equal amounts of which are added to the test solution. After boiling, a positive result is indicated by the formation of a brick-red precipitate of copper (I) oxide. Web• Fehling’s solution o Solution A – Dissolve 17.32g of copper ( II) sulphate (CuSO4.5H2O) made up to 250cm3 in a standard flask. o Solution B – Dissolve 86.5g of sodium potassium tartrate in warm water. Dissolve 30g of sodium hydroxide in water. Mix the two solutions and make up to 250cm3 in a standard flask.

Uses advised against Food, drug, pesticide … 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.
