Non reducing sugars do not react with Benedict's reagent. After the test, sample without reducing sugars remains the same, blue.
When reducing sugars are present in the sample, we can consider four results after the test is completed: a) green, low amount, that is 0.1 to 0.5% of reducing sugars in solution; b) yellow, low amounts of reducing sugars, 0.5 to 1.0%; c) orange, moderate content of reducing sugars, 1.0 to 1.5% of reducing sugars present; and c) brick red, large amount of reducing sugars in solution, 1.5 to 2.0%.

What compound can be oxidized by both Benedicts solution and Tollens reagent?
A reducing sugar such as glucose can be oxidized by both Benedicts solution and Tollens reagent to form a colored precipitate. This reaction is used to test for the presence of reducing sugars in a solution.
Do eggs test positive in benedicts test?
Yes, eggs can test positive in the Benedict's test because they contain glucose, which is a reducing sugar that reacts with the reagent in the test to form a colored precipitate.
What does Benedicts reagent do to the reducing sugar?
Benedict's test is based on Benedict's reagent, a liquid that changes color based on the sugar content of the material put in. Ketohexose acts as a reducing sugar because benedict's reagent is comprised of sodium citrate, sodium carbonate, and cupric sulfate. The cupric sulfate reacts with the ketohexose, reducing it and causing it to precipitate as cuprous oxide, which is what changes the color of the reagent and determines the sugar content.
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 chemical is used to test for reducing sugar?
Benedict's solution is commonly used to test for reducing sugars in a sample. It reacts with reducing sugars such as glucose and fructose to produce a color change from blue to green, yellow, orange, or red, depending on the amount present in the sample.
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 compound can be oxidized by both Benedicts solution and Tollens reagent?
A reducing sugar such as glucose can be oxidized by both Benedicts solution and Tollens reagent to form a colored precipitate. This reaction is used to test for the presence of reducing sugars in a solution.
If corn oil is tested with Benedicts's solution and Biuret reagent and the final color is blue what do you know about corn oil?
Benedict's solution tests for aldehyde which is present in reducing sugars. If the solution remained blue than no reducing sugar's are present in corn oil.
Would benedicts reagent show sugar in potato juice?
Yes, Benedict's reagent can be used to detect the presence of reducing sugars, such as glucose, in a solution. If potato juice contains glucose or other reducing sugars, it will react with Benedict's reagent to form a colored precipitate, indicating the presence of sugar. This reaction is based on the reduction of copper (II) ions in the reagent to copper (I) oxide by the reducing sugars.
If benedicts reagent turns red what substance is present?
If Benedict's reagent turns red after adding it to a solution, it indicates the presence of reducing sugars such as glucose or fructose. The red color is a result of the reduction of copper (II) ions in the reagent to copper (I) oxide by the reducing sugars.
Will hydrolysed dextrine give positive response to Benedict test?
Yes, it should. Benedicts test will be positive for reducing sugars, and since glucose is such a sugar, and would be a product of dextrin hydrolysis, you should get a positive result with Benedicts reagent.
Do eggs test positive in benedicts test?
Yes, eggs can test positive in the Benedict's test because they contain glucose, which is a reducing sugar that reacts with the reagent in the test to form a colored precipitate.

Benedict's turns orange when heated in the presence of a?
reducing sugar. Benedict's reagent is a solution used to test for the presence of reducing sugars, which includes glucose and fructose. The color change to orange indicates a positive result for the presence of reducing sugars in the substance being tested.
What chemical is used to test for sugars?
Benedict's solution is commonly used to test for the presence of reducing sugars. When a reducing sugar is present, the solution changes color from blue to green, yellow, orange, or red, depending on the amount of sugar present.
