WebFehling’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. The test employed for this purpose is known as Fehling’s test.
