What is Fehling’s Solution?
In organic chemistry, Fehling’s solution is defined as a chemical reagent that is used to check the presence of aldehyde (-CHO functional group). Fehling’s solution acts as a mild oxidizing agent, it is dark blue in colour and basic in nature.

It is a chemical mixture made up of two chemicals: Copper Sulphate and Rochelle salt (Potassium Sodium Tartrate solution), which are known as Fehling A and Fehling B solutions respectively. This solution can be used to differentiate between ketone and water-soluble carbohydrates. It is used as a supplement to the Tollens’ Reagent Test.
The most important use of this solution is to carry out Fehling’s test, this test is used to check the presence of reducing sugar (for example, glucose). This solution was named after a German chemist Hermann von Fehling, who developed it in 1849.
Fehling’s Solution
Fehling’s Solution is a chemical reagent that is used to check the presence of aldehyde functional groups in organic compounds. It is also used to differentiate between water-soluble carbohydrates (like glucose, fructose, etc.) and ketone(-C=O-) functional groups.
