Benedict's test for sugars

---

Benedict's reagent in a 1% sugar solution. Benedict's reagent is a solution of copper (II) sulphate (CuSO4), tartaric acid and sodium hydroxide. It is used in the Benedict's test to detect sugars, and turns from blue to an orange/red colour when they are present. This colour is due to a precipitate that forms as the copper sulphate is reduced to insoluble orange copper (I) oxide. Certain sugars do not provide this result, such as sucrose.
