General information

Determination of Sugar

Fehling’s test:

Fehling’s test is used to identify reducing agents, such as aldehydes and reducing sugars. Combining the two separate solutions (Fehling’s I and Fehling’s II) produces a deep-blue tartrate-copper(II) complex. Adding a reducing sample then causes a red pigment consisting mainly of copper(I) oxide to precipitate out of the mixture. This change in colour does not happen in the presence of sucrose or ketones.
