WebBENEDICT'S TESTING FOR SIMPLE SUGARS INTRODUCTION Benedict's reagent is a reagent that detects the presence of simple sugars (monosaccharides and disaccharides). A positive test is measured by a color change. Benedict's reagent is blue. The color change depends on the quantity of sugar present. Light green indicates small quan- tities and. WebBenedict’s reagent, also known as Benedict’s solution, is a chemical reagent which is made up of a complex mixture of sodium citrate, sodium carbonate, and the pentahydrate of copper (II) sulfate.
