Benedict's reagent starts off light blue. (from the copper(II) sulfate)
As glucose levels in the solution rise the color will proceed as follows:
green, yellow, orange, red and brick red
The brown/red color comes from the formation of copper(I) oxide an insoluble precipitate.

What color is liquid Benedict?

Why non- diet soda change colour when react with Benedict solution?
the benedict itself is not oxidized, it just turn other element's colour due to change during chemical reaction.....
What is the colour given by a positive Benedict's tests on fructose?
brick red..
What colour is the colour when mixing saliva and water using the Benedict solution?
When mixing saliva, water, and Benedict's solution, the initial blue color of the Benedict's solution will change to green, yellow, orange, or red, depending on the presence and concentration of reducing sugars like glucose in the saliva. This color change is indicative of the amount of reducing sugars present in the solution.
What colour is Benedict's solution?
Benedict's solution is typically a royal blue color. It is commonly used in chemistry and biochemistry to test for the presence of reducing sugars in a solution.
What colour is pre come?
It is a transparent liquid.
What colour is pure liquid gold?
To be a liquid, the gold will have to be hot enough to be molten. When in that state the substance will be hot enough to give off visible light, and the colour of that light will depend on how hot the liquid is.
How benedict solution prepared?
A Benedict's solution is a solution of sodium citrate, sodium carbonate and copper sulphate, whose colour changes from blue to yellow to red in the presence of reducing sugars such as glucose.
What is the predominant colour of a can of 7-up?
Green - even though the liquid inside is clear colour.
What colour is mercury at room temperature?
It is a silvery liquid.
Why the Benedict's solution turn brick red colour when testing glucose content in urine?
Copper (I) oxide: Cu2O
What color does Benedict' s solution change in another solution?
The Benedict solution contains Copper ii ion so has blue colour. when this solution is allow to react with aldehydic compounds specially sugars the copper ii ions reduce to cupric oxide so colour changes blue to red or pink.
