Acid Test

I thought that our lab today was very interesting. In my groups acid tests, we found that vinegar and lime juice had the biggest affect on baking soda. There was a lot of fizz (a full reaction) when combining vinegar and baking soda, as well as lime juice and baking soda. I was a little surprised that both pink and white grapefruit and orange juice did not have a bigger reaction to baking soda. I thought that those juices would be much more acidic than they were. The reaction that we got for these juices was about 1/4. My group also found that the actual pieces of fruit did not have a very great reaction to the baking soda. All of our results came in at under 1/4.
