Benedict's test is primarily used to detect reducing sugars, a type of carbohydrate macromolecule. The rationale behind the test involves the ability of reducing sugars to reduce copper(II) ions to copper(I) oxide in an alkaline solution, resulting in a color change that can be observed visually. A positive result, indicated by a color change from blue to green, yellow, orange, or red, suggests the presence of reducing sugars in the sample. This test is not applicable for non-reducing sugars or other types of macromolecules like proteins and lipids.
What else can I help you with?
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.
Would sucrose test positive or negative with benedicts reagent?
No, surcose is a disaccharide without a hemiacetal group
Why is sodium carbonate added to solution before Benedicts test is performed?
Sodium carbonate is added to increase the pH of the 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.
Which indicator would most likely yield a positive test by way of a color change in the water-cookie solution?
Benedicts solution

What is the test for sugar using Benedicts solution?
prosrdure of benidect solution test
Which is more sensitive test fehlings test or Benedicts test?
Benedict's test is more sensitive than Fehling's test for detecting reducing sugars in a sample. Benedict's reagent has a lower detection threshold and is known to give more accurate results compared to Fehling's reagent.
Why should you add 8 drops of urine in the Benedict test?
why should you add 8 drops of urine in the Benedicts test
What does a negative Benedicts test indicate?
A negative Benedict's test would indicate that there isn't any presence of reducing sugars in that particular substance.
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.

Who sells Benedect test solution?
Most chemical supply companies sell it. You can do an internet search for "retail sale of Benedicts solution".
Which indicator would most likely yield a positive test by way of a color change in the water-cookie solution?
Benedicts solution
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.
