About FEHLING'S SOLUTION NO.2

FEHLINGS SOLUTION NO.2 is a laboratory-grade analytical reagent used to detect reducing sugars like glucose. It is an odorless, blue liquid solution that reacts with reducing sugars to produce a red precipitate of copper(I) oxide. With a molecular formula of C4H4KNaO64H2O and a molecular weight of 248.22 g/mol, this solution is stored in tightly closed containers, soluble in water, and has a shelf life of approximately 1 year when stored correctly. Its slightly basic pH level of 7-9 makes it a reliable tool in chemical and biological laboratories for testing the presence of aldehydes or reducing sugars. Safety caution: it is poisonous and should be handled with care.
