Question

Imagine that you have been given to colorless solutions

describe how you could find out which of the contains the greatest concentration of reducing sugar you will need to think carefully about all the different variables that you would need to keep constant

Answer 1

Lithmus paper

Step-by-step explanation:

So um u need lithmus paper bc if its acid, you can see he color turns to red and base is blue. hope that helps!

Answer 2

To find out which solution has a higher reducing sugar concentration, perform a Benedict's test on equal volumes of each solution under the same conditions and compare the intensity of the red color produced.

Step-by-step explanation:

To determine which of two colorless solutions contains the greatest concentration of reducing sugar, one effective method is to perform a Benedict's test. Both solutions should be tested under identical conditions to maintain consistency. Safety is paramount, so wearing goggles during the experiment is essential.

Procedure for Benedict's test:

1. Measure equal volumes of each solution into separate test tubes.
2. Add a fixed number of drops of Benedict's solution to each test tube.
3. Heat the test tubes for the same amount of time in a water bath.
4. Observe and record the color change; the solution with a more intense red color indicates a higher concentration of reducing sugar.

The intensity of the red color formed is proportional to the amount of reducing sugar present, allowing you to determine which solution is more concentrated.
