Examples
- The Molisch reaction is a widely used biochemical test to detect the presence of carbohydrates in a solution.
- A positive Molisch reaction is indicated by the formation of a violet ring at the junction of the two liquids.
- The Molisch reaction involves the reaction of alpha-naphthol with sulfuric acid in the presence of carbohydrates, resulting in a characteristic violet color.
- To perform the Molisch reaction, a few drops of alpha-naphthol are added to the solution, followed by the addition of sulfuric acid, and the mixture is observed for the formation of a violet ring.
- The Molisch reaction is a simple and reliable method for detecting the presence of carbohydrates in a solution, and is commonly used in biochemistry and analytical chemistry laboratories.
