WebFeb 21, 2024 · One test for reducing sugars involves Fehling’s reagent, which contains Cu 2+ ions in an aqueous basic solution. If a reducing agent is present, the Cu 2+ is reduced to Cu + and forms a red precipitate of Cu 2 O. Therefore, if Fehling’s solution is added to a solution containing a reducing sugar, a red precipitate will form.
WebNov 14, 2024 · The Fehling test was developed in 1848 by Herrmann Fehling. Like Benedict’s test, it is also a sensitive test for the detection of reducing sugars.
