Forming the Violet Ring
Add two drops of reagent to the sample solution in a test tube and mix. Tilt the tube and let concentrated sulphuric acid run slowly down the side so it forms a separate layer underneath. A violet ring at the junction of the two layers shows a carbohydrate. The acid dehydrates the sugar to a furfural compound, which condenses with alpha-naphthol to give the coloured product; the test does not tell one sugar from another.
