Description

Alkaline Cupric Tartrate TS (Fehling’s Solution) is a blue liquid reagent commonly used in laboratory settings for testing reducing sugars, particularly in the determination of glucose levels. The solution consists of copper(II) sulfate and potassium tartrate dissolved in an alkaline solution, typically sodium hydroxide. When heated with a reducing sugar, it forms a red precipitate of cuprous oxide, indicating the presence of reducing substances. This reagent should be handled with care, as it contains caustic compounds and is sensitive to light.
