Question

Benedict's solution is used to test the presence of
A) Carbohydrates
B)Fats
C) Vitamins
D) Proteins​

Answer 1

Answer:

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.

Answer 2

The presence of (A) carbohydrates such as glucose can be tested using Benedict's solution.

Explanation:

• The combination of sodium carbonate, sodium citrate, and copper(II) sulfate pentahydrate at appropriate ratio yields a solution called as Benedicts solution.
• The normal color of this solution is blue.
• This reagent is used to test the presence of reducing sugars. Generally all monosaccharides are reducing in nature.
• Monosaccharides are one form of carbohydrates.
• When we heat sample containing reducing sugar such as glucose with benedicts reagent, the blue color of the solution turns into red.
• This happens as the copper present in copper (II) sulfate pentahydrate are reduced to copper (I) by sugars.
• Hence it is inferred that, Benedict's solution is used to test the presence of  A) Carbohydrates.
