Fehling's solution: Applications, Use of the reagent & Laboratory preparation

In organic chemistry, Fehling's solution (/'feɪlɪŋ/, FAY-ling) 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 Hermann von Fehling in 1849.
