This is due to the reduction of the cupric (Cu2+) ions in Benedict's reagent to cuprous form (Cu1+) by reducing sugars, forming cuprous oxide (Cu2O), which is a brick red precipitate. This is why Benedict's test is a good way to detect reducing sugars.

What are the Benedicts test results for glucose?
the solution will turn a 'brick red' colour if positive but will stay blue if negative.
Why does reducing sugar turn brickred with benedicts solution?
one of the components of Benedict's reagent is copper(II) oxide.when it is placed in solution with a reducing sugar, the copper(II) oxide is reduced to copper(I) oxide ions. this has a brick red colour. if there a small or large amount of the reducing sugar present, the color would range from green to brick red respectively.

How is Benedicts test used to determine the glucose content of a sample of urine in blood?
Aqueous is mixed with Benedict's reagent, a solution of copper sulfate, sodium hydroxide, and tartaric acid. The mixture is heated. Carbohydrates which react with Benedict's reagent to reduce the blue copper (II) ion to form a brick red precipitate of copper (I) oxide are classified as reducing sugars.
What color is benedicts solution when mixed with bread?
because it contains glucose
When glycogen is added to benedicts reagent why would it remains blue?
Although glycogen is a carbohydrate, it is classified under POLYSACCHARIDES which are non-reducing sugars. Benedict's reagent is used to test for the presence of non-reducing sugars. The positive result for this is a brick-red precipitate or solution. It remained blue (which is negative) due to fact that ALL POLYSACCHARIDES (such as glycogen) ARE NON-REDUCING SUGARS > I'm a Nursing Student. >M.J.T.M.E.

How do red factor canaries turn red?
The red canary was developed by a breeder named Dr. Hans Duncker. It can turn red because it was bred with a gene that causes this to happen.
