yes because the glucose molecules contain available reactive carbonyl groups- ketones or aldehydes which lose electrons (hence- reducing) to ions in the copper sulfate in Benedict's solution. a reaction between the ions and oxygen occur to create cuprous oxide which makes a brick red colour

What causes the reaction between glucose solution and sodium hydroxide?
The reaction between glucose solution and sodium hydroxide is a chemical reaction that involves the hydrolysis of glucose molecules by the strong base (sodium hydroxide). This reaction results in the formation of sodium gluconate and water. The hydroxide ions from the sodium hydroxide cleave the glycosidic bonds in glucose molecules, leading to the breakdown of glucose into simpler compounds.
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 are the Benedicts test results for glucose?
Benedict's test is a simple chemical test used to detect the presence of reducing sugars like glucose in a solution. The test result is positive if a brick-red precipitate forms, indicating the presence of reducing sugars. If the solution remains blue, it indicates a negative result.
What is the reaction between glucose and acidified potassium dichromate and Chemical Equation?
The reaction between glucose and acidified potassium dichromate is the oxidation of glucose to form gluconic acid. The chemical equation for this reaction is: C6H12O6 + H2Cr2O7 + H+ -> C6H11O7COOH + Cr2(SO4)3 + H2O
Reaction between glucose and copper oxide with lime water?
When glucose reacts with copper oxide in the presence of lime water, a redox reaction occurs where glucose is oxidized to produce carbon dioxide and water. The copper oxide is reduced to copper metal. The lime water is not directly involved in the reaction but can be used to test for the presence of carbon dioxide produced in the reaction.
What is benedicts solution used to find?
Glucose
What color is benedicts solution when mixed with bread?
because it contains glucose
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 causes the reaction between glucose solution and sodium hydroxide?
The reaction between glucose solution and sodium hydroxide is a chemical reaction that involves the hydrolysis of glucose molecules by the strong base (sodium hydroxide). This reaction results in the formation of sodium gluconate and water. The hydroxide ions from the sodium hydroxide cleave the glycosidic bonds in glucose molecules, leading to the breakdown of glucose into simpler compounds.
What does Benedicts reagent do?
It tests for glucose.
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.
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.
Does benedict's solution need heating when testing for glucose?
Yes, Benedict's solution needs heating to test for glucose. Heating helps to facilitate the reaction between glucose and the copper ions in the Benedict's solution, resulting in a color change that indicates the presence of glucose.
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.
What are the products of a condensation reaction between glucose and fructose?
The products of a condensation reaction between glucose and fructose are sucrose and water. In this reaction, a glycosidic bond forms between the glucose and fructose molecules, resulting in the formation of the disaccharide sucrose. Water is also produced as a byproduct of the condensation reaction.
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 reaction between sodium bicarbonate and glucose?
nothing
