Question [CLICK ON ANY CHOICE TO KNOW THE RIGHT ANSWER]
What reagent is used to test for reducing sugars?
A
Biurets
B
Iodine
C
Lugol’s
D
Benedicts
Explanation: 

Detailed explanation-1: -Benedict’s reagent (often called Benedict’s qualitative solution or Benedict’s solution) is a chemical reagent and complex mixture of sodium carbonate, sodium citrate, and copper(II) sulfate pentahydrate. It is often used in place of Fehling’s solution to detect the presence of reducing sugars.

Detailed explanation-2: -Benedict’s test is a chemical test that can be used to check for the presence of reducing sugars in a given analyte. Therefore, simple carbohydrates containing a free ketone or aldehyde functional group can be identified with this test.

Detailed explanation-3: -Benedict’s reagent, also known as benedict’s solution is used in Benedict’s test for detecting simple sugars such as glucose. It is a bright blue solution that is prepared by mixing copper sulfate pentahydrate, sodium carbonate, and sodium citrate in distilled water.

Detailed explanation-4: -Benedict reagent is a chemical reagent containing a complex mixture of sodium carbonate, sodium citrate, and copper(II) sulfate pentahydrate. It is used in place of Fehling’s solution to detect reducing sugars if present. The tests which use this reagent are called the Benedict reagent test.
