To prepare Benedict's solution, dissolve copper(II) sulfate, sodium citrate, and sodium carbonate in water, then add distilled water to make a final volume. Heat the solution until it boils and let it cool before filtering. Adjust the pH to 12 with sodium hydroxide and store it in a dark bottle.
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.
