Fehling’s test is a classic qualitative analysis method used to detect the presence of reducing sugars, particularly glucose, in a solution. Named after the German chemist Hermann von Fehling, this test is based on the reduction of copper(II) ions to copper(I) oxide in the presence of reducing sugars. This article will delve into the definition […]
