Abstract
The purpose of this experiment was to determine which liquid antacid was the neutralizes stomach acid most efficiently with respect to pH. The liquid antacids used in this experiment include Gaviscon, Kaopectate, Mylanta, and Pepto- Bismol. The hypothesis for this experiment states that Gaviscon will be able to neutralize stomach acid most efficiently due to its higher amounts in aluminium hydroxide and magnesium carbonate. The procedure for this experiment included dissolving potassium chloride and table salt into hydrochloric acid to simulate the stomach acid. 10mL of liquid antacid was then inserted into the solutions and pH values were measured. In conclusion, the hypothesis for this experiment was supported, with Gaviscon neutralizing liquid antacids most efficiently, and Kaopectate least effectively.
