Gas Law Stoichiometry Through Airbag Simulation. The purpose of this lab is to determine the correct ratio of baking soda and vinegar that leaves leaves no appreciable amount of either reactant leftover and yet fully inflates the bag without bursting.
Gas Law Stoichiometry Through Airbag Simulation
Purpose- The purpose of this lab is to determine the correct ratio of baking soda and vinegar that leaves leaves no appreciable amount of either reactant leftover and yet fully inflates the bag without bursting.
Materials- Water, ziplock bag, graduated cylinder, scale, baking soda, vinegar, goggles, apron, thermometer, and calculator.
Variables-
Dependent- Amount of CO2
Independent- Vinegar
Controlled- Baking soda
Procedure-
- Calculate how much baking soda should be used
- Fill the bag with water and empty into graduated cylinder to find the volume of the bag
- Measure out amount of calculated baking soda
- Pour first trial amount of vinegar into bag and put it in one corner
- Add baking soda and put it in another corner
- Close the bag
- Mix the two and shake the bag
- Repeat with different amounts of vinegar
