The Molisch test is performed by combining a small reagent with the test solution in a test tube. Sulfuric acid is added slowly to the slightly tilted tube. The mixture will form a layer without further mixing. If the layer is purple, the test is positive for the presence of carbohydrates. If a green color appears, the test is negative.
The test is named after botanist Hans Molisch, a professor at the German University of Prague.Learn more about Chem Lab
