Conversion of Mass Investigation

When beginning the pop rocks/soda part of the lab, I believed that the reaction between the two would cause a effervescent release of carbon dioxide.


As you can see, that prediction was correct. A physical reaction occured, melting away the sugary coating off Pop Rocks, which reached the C02 in it, and it manifested itself as bubbles. These bubbles rose into the balloon, expanding it to this position:
However, I think the reaction could have been amplified if we used a less flat bottle, because then we would have more carbon dioxide. Also, I wonder if different flavors would magnify the amount of carbon dioxide released. Maybe a more acidic soda would cause some corrosive powers, getting to more of the CO2 pockets in pop rocks.

Next, we began the baking soda/vinegar half of the experiment.
Going in to this experiment, I predicted that the baking soda and vinegar together would create a bubbly reaction that would cause the balloon to inflate.

I feel my hypothesis was supported because of the large balloon inflation. Also, I believed that the baking soda and vinegar would create a larger balloon than the previous experiment, because of how simplistic and concentrated the baking soda and vinegar were, compared to having all the additives in soda and pop rocks.

(deep introspection)

Finally, all three of my hypothesis were correct. We also poured all of the vinegar back a beaker, and it had the same amount of vinegar in it! For this reason, I think this was an interesting lab to introduce the Law of Conversion of Mass. However, I wanted to weigh them at the start and the end to make sure they were the same weights. Also, I would like to see if I could somehow cause the carbon dioxide to release back into the soda, and see if it had a similar amount of fizz.
