Problem 20

What is the change in enthalpy 1H2 for a chemical reaction? How is H different from E? 2

Step-by-Step Solution:
Step 1 of 3

Conclusion In our experiment we tested the pH of different antacids to see which has the greatest effect on stomach acid. We hypothesized that the alka- seltzer tablet would reduce the acidity in the stomach acid the most, which it did. Our goal was to find out which antacid people should buy that will help most with stomach acid problems. The stomach acid had a pH of 1.5 before anything was added. When we added a dose of Pepto Bismol to one beaker, it changed the pH to 2.02, this was the least effective antacid we used. This antacid barely changed the acidity, meaning it would be the least helpful to any person having stomach acid issues, we would not recommend. The Gaviscon and the Tums tablets changed the pH about the same. The Tums beaker produced a pH of 5.82 and the Gavisco
