A brick red precipitate of copper(1)oxide is formed
Explanation
Glucose in this case is a reducing sugar, when mixed with benedict solution,the blue copper (11) ions in the benedict solution is reduced to form copper(1)oxide which forms a red precipitate.The color obtained in this experiment indicates the amount of sugar(glucose) in the solution.When in low amounts greenish precipitate is obtained.In higher amounts, a red precipitate is formed.Yellow and Orange colors indicate an intermediate concentration of glucose.
