Results
The experiment had three different parts. Each step I used the same amount of vinegar 250mL. The baking soda was the thing that changed. The first step I used 10g the second was 30g and the third was 50g. The 10g made the least amount of gas only making the balloon have a 20-inch circumference. The 30g balloon had a 25-inch circumference. The 50g balloon had a 26-inch circumference. The reason that the 50g balloon had almost the same amount of gas as the 30g balloon was that the vinegar is a limiting reaction. A limiting reaction is where there are two or more compounds in a reaction and one of the compounds runs out leaving excess of the other compound.
Conclusion
When the HC2H3O2 (l) and the NaHCO3 (g) reaction happened it made H2O (l), CO2 (g) and NaC2H3O2 (aq). this experiment would have ben better if the balloon was larger because the ten grams of baking soda already had the balloon fully stretched. so when I used 30 grams of baking soda the ballon filled to its max and then just compressed the gas.
