PH Lab

In this lab me and megan both selected 4 antacids to mix in vinegar. We then filled 4 cups with 25mL of vinegar. Next we took we picked out 4 different types of antacids to test in the vinegar. First we took the PH number of vinegar to see which antacid works best. Vinegar showed a PH number of 2 to start with. Next we started to add our antacids into the cups. Peppermint Antacid with the lowest milligrams was crushed into powder and mixed with the vinegar. Once mixed we took its PH number the the PH tape. Our results showed that the PH number is 5 because we compared its color to the key on the box. Next we took the Equate regular antacid and once again crushed it into powered to mix with the vinegar.  With the PH tape we took its PH number getting a 4. Rolaids had the next lowest dosage and so we crushed it and poured its powered into the vinegar filled cup. Mixed and tested, we came out with a PH number of 6. Finally Extra Rolaids Antacid had the highest dosage number and it was time to test it. Once it was mixed with the vinegar we took its PH number getting a 5. The results show the lowest dosage of Peppermint antacids and the highest dosage of Extra Rolaids both showed the same PH Number, 5. The Equate Regulars showed 4 with a lower PH number and Rolaids with a 6 being the highest PH number received in the entire experiment. Although both the lowest and highest dosage of  antacids showed the same results, meaning they work the exact same the Rolaids having a PH number of 6 shows it works better than all the other antacids used in the experiment.
