pH lab

When we did their lab, we first we found the lowest recommended dosage for the baking soda and each of the antacids and recorded them. Next we set out 4 cups and poured 25 mL of vinegar into each one of them and used the pH paper and its color scale to find the pH of it. We had to choose an antacid, crush it, add it to one of the cups of vinegar, stir it then wait 1 minute and record the data. When you have vinegar and baking soda together it acts like the acid in your stomach. so if you ever have time put some baking soda in a glass of vinegar and watch how it reacts. When we tested the generic version of antacid, its
 Ph level was the lowest and it didn't bubble very much. The tums had a higher Ph level than the generic one. This lab was interesting to me and it showed me how the different things you put in your stomach to help you feel better, react in your stomach.


Here is a graph that shows some examples of Ph levels of different antacids:
