Seliwanoff's Test?

Answer

Seliwanoff's test is a biochemical procedure used to detect ketonic sugars such a fructose and other similar compounds. The test is performed by dissolving resorcinol crystals in equal amounts of water and hydrochloric acid. The compound is then heated until it changes color. If red precipitate forms, the test is positive.
