About Tollen’s Test: Which food samples contain reducing sugars? Virtual Lab Simulation

Get Started Now

Techniques in Lab

Practice makes perfect! In this simulation you will learn how to perform Tollen’s test for reducing sugars on a variety of food samples. You will use your existing knowledge of food macromolecules to predict which food samples contain reducing sugars. Dr. One will guide you step-by-step to process the samples through Tollen’s test. How will your predictions compare to your results?

Make a prediction

Start by getting familiar with the apparatus on your workbench and setting up the heated water bath. Now that you’re set up, use your existing knowledge to predict which food samples will contain reducing sugars. Don’t be afraid to make mistakes. Later you will compare your predictions to your results.

Perform Tollen’s test

Learn how to process food samples through Tollen’s test as if you were in a lab! With step-by-step guidance from Dr. One, you will process the food samples through Tollen’s test and generate some shiny results. Combine the theory of Tollen’s test with your observations to interpret your results and discover which food samples contain reducing sugars. 

Results vs. Prediction

The final step is to compare your results to your predictions. Did your results match your predictions? Are there any results that are surprising?
