(also Benedict's reagent)
A chemical solution that changes colour in the presence of glucose and other reducing sugars, used in clinical urine tests for diabetes. It is a mixture of sodium or potassium citrate, sodium carbonate, and copper sulphate.
- Some sugars are known as reducing sugars (for example glucose and fructose) and they can be recognised by their ability to reduce hot Fehling's or Benedict's solution, producing a brick red precipitate of copper oxide.
- Place a piece of food in each test tube and then pour 30-40 ml of Benedict's solution over the food.
- Perhaps the reagent labeled Benedict's solution was made incorrectly and did not work to detect sugar
Named after Stanley R. Benedict (1884–1936), American chemist.
