Fehling's test is more sensitive than Benedict's test. It is a more reliable method for detecting reducing sugars, such as glucose and fructose, due to its two separate solutions that are mixed before use, allowing for more accurate results compared to the single solution used in Benedict's 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.
ulo nyo!!
yes.
Fehling test is used for reducing sugars.

prosrdure of benidect solution test
I think you are referring to the test using Fehlings solution. Fehlings solution oxidises aldehydes and ketones and formic acid and is in turn reduced. The red precipitate is the copper(I) oxide formed by reduction of the copper(II) complex found in Fehlings solution. Acetic acid is not readily oxidised and so there is no precipitate. See link for more information on what the complex is in Fehlings solution and how it is prepared.
Benedict's test is used to detect the presence of reducing sugars in the patient's urine, which may be indicative of conditions like diabetes. Fehling's test is used to detect reducing sugars in the blood, which can help in diagnosing conditions like diabetic ketoacidosis. Both tests provide valuable information for healthcare professionals to evaluate a patient's carbohydrate metabolism and diagnose related conditions.
Benedict's test and Fehling's test are both used to detect reducing sugars in body fluids (e.g. urine) that may indicate conditions like diabetes. In the tests, a reducing sugar like glucose reacts with the reagents to form a colored precipitate, indicating a positive result. This can help healthcare professionals diagnose and monitor patients with sugar metabolism disorders.
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.
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.
