Abstract: Antacids are weak bases which eliminate heartburn through the neutralization of HCl (hydrochloric acid) in small amounts within the stomach. Titration is the process by which one unknown solution’s concentration reacts within a known solution’s concentration (standardized solution). During this experiment, titration was used …… The best antacid between the Mylanta and Alka Seltzer was ….. Introduction: The purpose of the experiment was to use the titration process to calculate the amount of NaOH needed until the pH indicator changes color (to hit the endpoint). By already knowing the amount of moles of HCl initially within in the flask and amount of HCl moles neutralized by the NaOH, the moles of HCl neutralized by antacid can be calculated and

Unformatted text preview: determined. The hypothesis for this experiment was that the Mylanta was the best antacid because it cost the most money to buy over the counter. Also, the Mylanta had the cheaper cost per dose, so it could be more effective against heartburn and be the leading brand, based on the economic-friendliness. For calculating the effectiveness of the two antacids, Equation 2 was used: Moles of HCl (antacid neutralized/gram) = Moles of HCl (antacid neutralized) / grams antacid used The purpose of the experiment was to determine the best antacid between Mylanta and Alka Seltzer, based on the amount of antacid to be used in each, cost, and size per container.
