Today in class we finished finding the pH of different substances. We needed to have a total of 15. After we finished that we got into 4 groups of 6 or so and found the probes of the substances we tested. The machine that I was at wasn't working like it was supposed to so Mrs. Sorensen had to help us. She had to clean the pH sensor because there was another older substance on it. After it was clean it started to work correctly. In my group we only had time to test the Gatorade and Juicy Juice. For the Gatorade the pH paper said 3 and the prob said 3.02. For the Juicy Juice I got 2 on the pH and 3.88 for the prob.
