What is barfoed's solution?

Answer 1

Barfoed's reagent consists of a 0.33 molar solution of neutral copper acetate in

1% acetic acid solution

Answer 2

Barfoed's solution is a reagent used to test for the presence of reducing sugars, specifically monosaccharides like glucose. It is copper acetate in acidic solution, which forms a brick-red precipitate when heated with a solution containing reducing sugars. The test is based on the reduction of cupric (Cu2+) ions to cuprous (Cu1+) ions by the reducing sugars.
