how are the conditions of barfoed's test different from those benedict's test?

Answer 1

The tests are extremely similar. Barfoed's test detects monosaccharides through a reduction reaction that precipitates copper(I) oxide (which is red in color), and Benedict's reagent detects reducing sugars by producing the same precipitate. The only real difference is that Benedict's produces a greater volume of precipitate, and the precipitate can vary in color depending on the amount of sugar present.
