What does the Benedict's solution test show?

A colour change from the original blue to a brick red colour, although various intermediary colours can also form depending on the concentration of the glucose.
if reducing suger is present the colour of the solution will turn to brick red and that will be a positive test.

my answer: Benedict's reagent contains copper sulphate, since glucose is educing sugar it will turn Cy +2 into a reagent , to cu +1.
