Barfoed's test is a copper reduction test but unlike Benedict's test, it is carried out in an acid (pH 4.6) rather than alkaline solution. This video lesson demonstrates the procedure in the qualitative test for carbohydrates. Barfoed's test distinguishes monosaccharides from disaccharides. The procedure covers the description of the laboratory instruments and materials that are used in such tests.
At the end of the procedure, an observation of the test result is made and interpreted and a well balaced reaction equation is obtained.
