In [[organic chemistry]], '''Fehling's solution''' is a chemical [[reagent]] used to differentiate between water-soluble [[carbohydrate]] and [[ketone]] ({{chem2|>C\dO}}) [[functional group]]s, 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.<ref>{{cite journal
