Transcript of Tums v. Alka Seltzer

Acknowledgments We would like to thank McGehee School for funding our intensive research We would like to thank Dr. Cresson for providing us this opportunity and her never-ending help We would like to thank Prezi for being user friendly and awesome We would like to thank Tums and Alka-Seltzer for being so perfectly examinable We would like to thank Tums for being magically delicious We would like to thank Alka-Seltzer for being so fantastically fizzy and full of fun Finally: We would like to thank hydrochloric acid for digesting food and giving Tums and Alka-Seltzer reason for existing General Information Tums vs. Alka-Seltzer Tums Materials and Methods Crush up antacid (Tums or Alka seltzer) then put in weigh boats Conclusion We concluded that Alka-Seltzer was more effective at neutralizing hydrochloric acid.

It should be noted that the Alka-Seltzer trials had much a higher range and percent variation compared to the Tums trials, though both were still relatively low. Results Conclusion (cont.) To improve our method, we would like to find a more effective way of combining the antacid and the acid.

If we were to continue these experiments, we would like to test Alka-Seltzer against other antacids like Pepto-Bismal or generic brands to see how it would compare. The timeless tale of a neutralization reaction Alka-Seltzer 750 mg of calcium carbonate
Serving size - 2 tablets 100 mg of anhydrous citric acid
1916 mg of sodium bicarbonate
Serving size - 2 tablets Love, Emily, Olivia, Jenna, and Lydia Pour 25 mL of 0.1 M of HCl and pour into a beaker Add crushed antacids to the acid. Measure the pH of each solution with a pH probe Emily Adams, Olivia Primeaux, Lydia Netterville, Jenna H. Alka Seltzer would be more effective in neutralizing stomach acid because it has multiple active ingredients. 2HCl + CaCO 3 H CO + CaCl 2 3 2 HCl + HCO H CO + Cl 3 2 3
