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.
What is the test for sugar using Benedicts solution?

What is the stain solution when chemical is test for sugar?
It is normally benedicts solution. Add about 1/4 of the total sugar solution to a test tube and heat it in a hot water bath at around 50 degrees C for 5 min. For example, heat 40mL of sugar water (C12H22O11 aq ) with 10mL of Benedicts soluton (copper and sodium salts). If it is a positive test it will turn yellow.
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 indicator for carbohydrates?
Simple(sugar): benedicts solution. Turns bright orange. Complex(starch): iodine turns dark purple/black
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.
What was the colonial reaction to the sugar act?
The colonial reaction to the sugar act was smuggling sugar and molasses.
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.
When was St. Benedicts Harps GAC created?
St. Benedicts Harps GAC was created in 1983.
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.
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.
