Question

Why does Benedict's or Fehling's solution give
red - brown or orange-yellow precipitate with
reducing sugar like glucose ar fructose?

Answer 1

Answer:

When Benedict's solution and simple carbohydrates are heated, the solution changes to orange red/ brick red. This reaction is caused by the reducing property of simple carbohydrates. The copper (II) ions in the Benedict's solution are reduced to Copper (I) ions, which causes the color change.
