Benedict's solution changes color based on the presence of reducing sugars. Initially, it is blue, but when heated with a reducing sugar, it can change to green, yellow, orange, or brick-red, depending on the concentration of the sugar present. A higher concentration results in a more intense red color. This color change is used as an indicator in biochemical tests to detect sugars.
What else can I help you with?
Which indicator would most likely yield a positive test by way of a color change in the water-cookie solution?
Benedicts solution
What color does benedicts' turns if no sugar were present?
Egg yolks have a natural white or pale yellow color. Without the addition of sugar, egg yolks will not change color when heated in the classic Eggs Benedict dish.
Why the color of benedicts solution change when heated?
The color change in Benedict's solution when heated is due to the reduction of copper ions in the solution. Initially, the blue-colored Cu(II) ions in Benedict's solution are reduced to form a reddish-brown precipitate of Cu(I) oxide. This color change indicates the presence of reducing sugars in the solution.
How does Benedicts solution work with sugar?
Benedict's solution is a chemical reagent used to test for the presence of reducing sugars, such as glucose. When heated with a reducing sugar, such as glucose, in the presence of an alkali (sodium carbonate), a redox reaction occurs, causing the blue color of the Benedict's solution to change to a brick-red precipitate of copper oxide. The intensity of the color change is proportional to the amount of reducing sugar present in the solution.
What is the difference between Benedict's Reagent and Biuret Reagent?
Benedicts reagent is used to check reducing sugars , it need hat to work and gives red color when positive ,. While biuret reagent is for proteins .there is no need to use heat and gives purple , violet color when positive ..

What color is benedicts solution when mixed with bread?
because it contains glucose
Why the color of benedicts solution change when heated?
The color change in Benedict's solution when heated is due to the reduction of copper ions in the solution. Initially, the blue-colored Cu(II) ions in Benedict's solution are reduced to form a reddish-brown precipitate of Cu(I) oxide. This color change indicates the presence of reducing sugars in the solution.
What test show hydrolysis of proteins?
The biuret test can be used to show the hydrolysis of proteins. In this test, a blue to purple color change indicates the presence of peptide bonds being hydrolyzed. This color change occurs due to the formation of a coordination complex between copper ions and the peptide bonds.
When did Sarah Bosmans-Benedicts die?
Sarah Bosmans-Benedicts died in 1949.
When was Sarah Bosmans-Benedicts born?
Sarah Bosmans-Benedicts was born in 1861.
When was St. Benedicts Harps GAC created?
St. Benedicts Harps GAC was created in 1983.
Which white powder turns orange in benedicts solution?
The white powder that turns orange in Benedict's solution is glucose. Benedict's reagent contains copper ions which can be reduced by glucose, resulting in a color change from blue to orange-red.
Would raffinose react with benedicts reagent?
Benedicts reagent tests for reducing sugars, so the question is, is raffinose a reducing sugar. Raffinose is a trisaccharide made up of glucose, fructose and galactose. It is not a reducing sugar because all of its anomeric carbons are bonded, so it will not react with benedicts reagent.

What does Benedicts reagent do?
It tests for glucose.
