Here is the chemical equation that represents the breakdown of sugar:
For this lab, you will compare experimental and theoretical results for how much carbon dioxide (CO2) is produced when sugar (C12H22O11) is broken down in water (H20), using yeast as a catalyst.
Materials:
- 4 packets of quick rise yeast (we will use 2 packets but it is good to have extra on hand just in case)
- a small soda or water bottle (500 mL)
- 1/4 cup of white sugar (we will use 1 tsp = 5 mL, but it is good to have extra on hand just in case)
- 3 balloons (we will use 1 balloon, but it is good to have extra on hand just in case)
- 1 meter of string
- 1 teaspoon measuring spoon
- a balance for measuring mass (optional)
- a meter stick
