A solution used in Fehling’s test to detect sugar in urine [Described 1848. After Hermann Christian von Fehling (1812-85), Professor of Chemistry at Stuttgart, Germany.]
Solution of copper sulfate, potassium tartrate, and sodium hydroxide used to test for sugar (especially glucose) in the urine, which, when present, turns the solution reddish.
A solution used for detecting the presence of sugar in urine. There are two components: Fehling’s I (a copper sulfate solution) and Fehling’s II (a solution of potassium sodium tartrate and sodium hydroxide), which are kept separate until required for use. Boiling Fehling’s solution (equal amounts of Fehling’s I and II) is added to an equal volume of boiling urine; a yellowish or brownish coloration indicates the presence of sugar.
A solution that includes a copper salt that can be readily reduced and is employed to detect the presence of sugar in urine.
