A-B-C . . . As Easy as Acidity

CSEF · 2003 Pharmacology/ Toxicology

Alexandria C. Brown · Merryhill School at Brookside, Stockton

Overview

Objectives/Goals The purpose of this project was to determine which non prescription antacid lowers the acidity in a person's stomach the most potently. My hypothesis was that pepdo-Bismol brand antacid would lower the acidity of the hydorchloric acid solution the most noticeably because of its higher concentration in the active ingrediant, Bismuth Subsalicylate, above the other brands. Methods/Materials The experiment involed testing the pH of a hydrochloric acid solution once mixed with different brands of antacids. The antacids used were all chewable tablets that are mild enough to use without a prescription. 10ml of a hydrochloric acid solution was used to represent the hydrochloric acid in a person's stomach and the ph level of the solution once mixed with the antacids represented how much the antacid actually lowered the acidity level of the solution. Results The control or untouched data,which in this case was the hydrochlorcic acid solution with no added variables had a pH of 4. Pepcid-AC recieved 4.5. Zantac 75 read 4.5 aswell. Cimetidine 200 had a pH of 5. Pepto-Bismol which lowered the acidity level of the hydrochloric acid solution the most noticebly had the pH of 6. Conclusions/Discussion In conclusion, my hypothesis was proven correct. Earlier in my hypothesis i stated that Pepto-Bismol would lower the acidity of the hydrochloric acid solution the most noticebly because of its high concentration in its active ingrediant. The experimental data supported my hypothesis,indicating that Pepto-Bismol actually does cope with sotmach acid complications more effectively that other brands. With this new found information scientist may be able to expand this project by developing a stronger antacid using some of the same active ingrediants. This new developed antacid could possibly treat more serious acid compliations such as Acid Reflux disease and Ulcers.

Summary statement

The purpose of my project was to test to see which antacid lowers the acidity in your stomach the most using 5 different brands.
