Benedict's solution in a dropping bottle
Laboratory bottle of Benedict's solution with a dropper and beaker. This solution is used in laboratories to test for the presence of sugars. Also known as Benedict's reagent, it is a solution of copper (II) sulphate (CuSO4), tartaric acid and sodium hydroxide. In the presence of sugars, the copper sulphate is reduced to insoluble copper (I) oxide. The current UN Globally Harmonized System of Classification and Labelling of Chemicals (GHS) label indicates that this chemical is environmentally hazardous (GHS09). As well as the symbol there is a signal word and suppliers provide numbered statements (H412) that is harmful to the aquatic life with long lasting effects.
