Yes!
Hypothesis: If we mix pop rocks and soda, then the pop rocks will add carbonation to the soda and make it fizz. I think that the pop rocks and soda will have a similar reaction to vinegar and baking soda.
Was the hypothesis correct?
No!
Why?
The first test we preformed was the pop rocks and soda test. When the pop rocks were added to the soda they fizzed, but only a little. And the pop rocks did not create more carbonation in the soda. They mostly created a gas. This is why we placed a balloon over the top of the bottle. The second test was preformed the same way but instead we used baking soda and vinegar. When we put the balloon over these they created a large amount of gas. So far it sounds like the two reactions are quite similar, but they are not. The gases they released were created in different ways. The gas from the soda was not created by a chemical reaction but a physical one. The pop rocks and soda contained the CO2 gas that was released when the soda and pop rocks met. But when the second test was preformed a chemical reaction occurred, vinegar + CaHCO3 -> CO2. They created the same gas but in a different way.
Problems:
LAB TEST ONE:
When we were putting the balloon on the soda it got a hole in it. We thought we could fix the problem by plugging it with our finger, but we couldn't. So all of our gas escaped, and our balloon did not blow up like it was supposed to.
LAB TEST TWO:
There really were no problems with the second test. One problem that may be able to be classified as a problem is that when we removed the ballon from the bottle it looked like not all of the baking soda had made it into the vinegar. When we finished the test we poured the vinegar back into the graduated cylinder to see if there was more, less, or the same amount. To us it looked like there was more but that could have been because of the gas that hadn't been released already.
