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 reagent, also known as Benedict’s solution, is a chemical reagent which is made up of a complex mixture of sodium citrate, sodium carbonate, and the pentahydrate of copper(II) sulfate.
Detailed explanation-3: -Benedict’s reagent is the solution used in Benedict’s test to detect simple sugars such as glucose. It is a bright blue solution prepared by mixing copper sulfate pentahydrate (CuSO4. 5H2O), sodium citrate (Na3C6H5O7), and sodium carbonate (Na2CO3) in distilled water.
