How do you test for glucose Benedict's solution?
In respect to this, is Benedict's solution used to test for glucose?
Benedict's solution (Fehling's solution) is used to test for simple sugars such as glucose. In the presence of simple sugars, the blue solution changes color to green, yellow, and brick-red, depending on the amount of sugar.
Secondly, how do you make Benedict's solution? One litre of Benedict's reagent can be prepared by mixing 17.3 grams of copper sulfate pentahydrate (CuSO4. 5H2O), 100 grams of sodium carbonate (Na2CO3), and 173 grams of sodium citrate in distilled water (required quantity).
Keeping this in view, how do you do a Benedict's test for reducing sugars?
Benedict's test for reducing sugars
- Place two spatulas of the food sample into a test tube or 1 cm 3 if the sample is liquid.
- Add an equal volume of Benedict's solution and mix.
- Place the tube in a water bath at about 95°C for a few minutes.
- Record the colour of the solution.
How do you test for sugar in a solution?
To test for sugar, you add the Benedict's solution to the tube with your sample. Then, the sample is heated in a water bath for about five minutes. This helps the reaction occur between the Benedict's solution and the sample. If sugar is present, the Benedict's solution will change color.
