How is the Molish test performed?
The Molisch test is a chemical test that is used to detect the presence of carbohydrates, specifically the presence of certain types of sugars in a given sample. The test involves adding a few drops of alpha-naphthol, a solution of naphthol in alcohol, to the sample being tested. Followed by adding concentrated sulfuric acid to create a purple ring at the junction of the two layers. The purple ring indicates the presence of carbohydrates, specifically the presence of the sugar component. This test is commonly used in biology and biochemistry laboratories to analyze the presence of carbohydrates in various samples.
