Vedclass · Answer

(A) Benedict's solution is a chemical reagent used to test for the presence of reducing sugars like glucose.When glucose reacts with Benedict's solution,it reduces the copper$(II)$ ions $(Cu^{2+})$ to copper$(I)$ oxide $(Cu_2O)$.The color of the precipitate depends on the concentration of the reducing sugar present.- $A$ green precipitate indicates a low concentration of reducing sugar.- $A$ yellow to orange precipitate indicates a moderate concentration.- $A$ brick-red precipitate indicates a high concentration of reducing sugar.- $A$ violet precipitate is not formed in this reaction; it is characteristic of the Biuret test for proteins.

Glucose on reacting with Benedict's solution may give the following precipitates except:
