How Sucrose Is Tested
Sucrose is a non-reducing sugar, so alone it leaves the mixture blue. Boil the sample with dilute hydrochloric acid to split it into glucose and fructose, neutralise with an alkali such as sodium hydrogencarbonate, then add equal volumes of solutions A and B and heat in a boiling water bath. A brick-red precipitate of copper(I) oxide confirms the sugars set free.
Keeping A and B Apart
The two solutions are stored in separate bottles and mixed only just before use, because the combined reagent does not keep.
