Question
If a reducing sugar is present what colour will Benedict's solution change to?
Solution
If a reducing sugar is present, Benedict's solution will change to a range of colors from green to yellow or brick-red, depending on the amount of sugar. Here are the steps:
- Prepare a test tube with the solution you want to test for reducing sugars.
- Add an equal volume of Benedict's reagent to the test tube.
- Heat the mixture in a boiling water bath for about 5 minutes.
- Observe the color change. If the solution turns green, it indicates a small amount of reducing sugar. A yellow to orange color indicates a moderate amount, and a brick-red precipitate indicates a high amount of reducing sugar.
