Fehling’s solution is a deep blue alkaline solution which is used to identify the presence of aldehydes or groups that contain any aldehyde functional group -CHO and in addition with Tollen’s reagent to differentiate between reducing and non-reducing sugars. Fehling’s solution is also used to differentiate a … See more Fehling’s solution is prepared just before its actual use. It is done by mixing equal volumes of two previously made solutions, a deep blue Fehling’s solution A, which is 70 grams of cupric sulphate pentahydrate per litre of solution … See more Fehling’s test was first carried out by a German chemist Hermann von Fehling in 1849. In this test, the heating of aldehyde with Fehling’s Reagent/solution is done. This process will subsequently result in the formation of a … See more The reaction between copper(II) ions and aldehyde in Fehling’s solution is represented as; RCHO + 2 Cu2+ + 5 OH− → RCOO− + Cu2O + 3 H2O When tartrate is added, the … See more WebApr 6, 2024 · The Tollens’ reagent is a solution of freshly prepared ammoniacal silver nitrate with the chemical formula Ag(NH 3) 2 OH.

WebSchiff Reagent Composition. Schiff reagent is prepared by using fuchsin (<1%) dye in water (>98%) combined with sodium bisulfite (<1%) dissolved in solution of hydrochloric acid (<1%). The solution is shaken at intervals followed by decolorization with charcoal. The mixture is then filtered. WebBenedict's reagent can be prepared from sodium carbonate, sodium citrate and copper(II) sulfate. It is often used in place of Fehling's solution. Benedict's reagent contains blue copper(II) ions (Cu2+) which are reduced to copper(I) (Cu+). These are precipitated as red copper(I) oxide which is insoluble in water. Chemical test: WebFehling's solution is used as a chemical test used to differentiate between water-soluble aldehyde and ketone functional groups, and as a test for monosaccharides.The test was developed by German chemist Hermann … idf cyber unit
