Benedict's test estimates on color scale the presence of sugar .Normally used as a random pathological chemical test to determine the presence of sugar in urine in Diabetes patients.In presence of sugar Benedict's solution turns from blue to shades of yellow,red,brown & dark according to the percentage of sugar present in solution on heating the solution.
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.
The biuret test can be used to show the hydrolysis of proteins. In this test, a blue to purple color change indicates the presence of peptide bonds being hydrolyzed. This color change occurs due to the formation of a coordination complex between copper ions and the peptide bonds.
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.
There are 4 colors that can be observed in Benedict's test. This is a test that is conducted to show if there is a presence of reduced sugars. This test is also referred to as Benedict's reagent.

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.
why should you add 8 drops of urine in the Benedicts test
A negative Benedict's test would indicate that there isn't any presence of reducing sugars in that particular substance.
No, surcose is a disaccharide without a hemiacetal group
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.
Sodium carbonate is added to increase the pH of the solution.
Most chemical supply companies sell it. You can do an internet search for "retail sale of Benedicts solution".
