Answer Posted / fisa
The test was devised by German chemist Herman von Fehling.
Fehling's reagent consists of two solutions.
Fehling A and Fehling B .Fehling A contains CUSO4.5 H20 and
Fehling B contains alcoholic sodium / potassium tartarate.
When the two solutions are mixed in equal amounts a clear
blue solution results for the tartrate forms a soluble
complex with the copperhydroxide produced.this solution is
widely used as an oxidising agent preferably in
quantitative sugar determinations.
