Almost all the antacids that have the same active ingredient work the same amount as the other. The results of the experiment were that the antacid Tums neutralized the most stomach acid. My hypothesis was that the antacid Tagamet would neutralize the most stomach acid. The results indicate that this hypothesis should be rejected. I think Tums neutralized the most stomach acid because it has calcium carbonate in it.
Calcium carbonate is proven to be highly alkaline.
Because of the results of this experiment, I wonder if the amount of buffer in the antacid had an effect on how much stomach acid the antacid neutralized. If I were to conduct this experiment again I would make more observations on the experiment. I also would use phenolphthalein as an indicator of when an acid is neutralized. The following information will help people understand how stomach acid works and what antacid will help them most. Stomach acid is highly acidic and has a pH of 1.6.
