Benedict's solution is a chemical reagent used to test for the presence of reducing sugars, such as glucose and fructose. It contains copper(II) sulfate, sodium carbonate, and sodium citrate, which react with reducing sugars when heated, resulting in a color change from blue to green, yellow, or red, depending on the sugar concentration. This test is commonly utilized in laboratory settings for food analysis and medical diagnostics, particularly in Diabetes management.
Because this solution contain copper(II) sulfate.
Sodium carbonate is added to increase the pH of the solution.
Benedicts solution
A reducing sugar such as glucose can be oxidized by both Benedicts solution and Tollens reagent to form a colored precipitate. This reaction is used to test for the presence of reducing sugars in a solution.
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.
