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.
Stomach acid is hydrochloric acid produced by the stomach.
If there is too much stomach acid it can cause heartburn. Heartburn is when stomach acid is produced in abnormal amounts or location. One of the symptoms of heartburn is a burning feeling in the chest or abdomen. They can be recognized by their sour taste and their ability to react with other substances. Acids are confirmed as an acid by their pH. The pH of acids range from 0-6.9.
