Seliwanoff's test is a chemical test that is performed to differentiate between a ketone hexose and aldehyde sugar. The test is named after the chemist who developed the test, Theodor Seliwanoff.Continue Reading
In Selwanoff's test, ketone hexoses, which are carbohydrates with six carbons, will turn a deep red when they react with the reagent. An aldehyde hexose will turn a light pink when it reacts with the reagent. Ketone hexoses will form a color much more rapidly than the aldehyde hexoses.
To perform the test, chemists add about 2 milliliters to test tubes containing 10 drops of the sugar being tested. The test tubes are then heated in boiling water. After about 1 minute, the deep red will appear if a ketone hexose is present.Learn more about Chem Lab
