Does using benedicts reagent on honey produce a positive result?
Yes, Benedict's reagent can produce a positive result when used on honey containing reducing sugars, such as glucose or fructose. The reagent will change color from blue to green, yellow, orange, or red depending on the concentration of reducing sugars present in the honey.
Wll Ribose will turn Benedict's solution red?
Yes, Ribose will turn Benedict's solution red because it is a reducing sugar. Benedict's solution changes color when it reacts with reducing sugars like ribose due to the formation of a red-orange precipitate of copper(I) oxide.
How do you tell the difference between glucose and maltose using benedicts reagent?
Benedict's reagent can be used to differentiate glucose and maltose based on their reducing sugar properties. Glucose is a monosaccharide and will readily reduce Benedict's reagent to form a brick-red precipitate, indicating a positive test. Maltose, being a disaccharide composed of two glucose units, will also react with Benedict's reagent but may produce a less intense color change compared to glucose due to its structure.
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.
What colour is a millon's reagent when mixed with egg albumin after heating?
A Millon's reagent mixed with egg albumin and heated would turn red. This color change occurs due to the reaction between the phenolic compounds in Millon's reagent and the tyrosine residues in the protein.
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.
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.
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 ..
Does using benedicts reagent on honey produce a positive result?
Yes, Benedict's reagent can produce a positive result when used on honey containing reducing sugars, such as glucose or fructose. The reagent will change color from blue to green, yellow, orange, or red depending on the concentration of reducing sugars present in the honey.
What color will sucrose turn when mix with seliwanoff reagent?
the solution turns to deep red...
Wll Ribose will turn Benedict's solution red?
Yes, Ribose will turn Benedict's solution red because it is a reducing sugar. Benedict's solution changes color when it reacts with reducing sugars like ribose due to the formation of a red-orange precipitate of copper(I) oxide.
Would glucose solution produce a positive Benedicts test?
No, Benedicts reagent will show positive results if the carbohydrate is a reducing sugar. You will know if it is positive if the sample will turn from blue to green then to orange when you are cooling the solution, which is the last step when you are performing the benedicts test for carbohydrates.

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
