Antacids Lab
Introduction The purpose of this lab was to test different antacids, to find out which would be the most effective to take. Stomach acid problems come from a overproduction, and build up of gastric acid (HCl). In order to determine which antacid is the more effective, four different brands of antacids were chosen, and tested. The purpose of an antacid is to balance out the pH inside a person's stomach. PH is the measurement of molar concentration of hydrogen ions that are present in the solution (N. Tro, 733-735). If this experiment were to be repeated, it would be to show which antacid would be more effective to buy as a consumer. In this experiment an antacid is dissolved in HCl, and then titrated NaOH is added into the antacid solution until the color turned from clear to a pink. The amount of mL of NaOH needed to turn the solution pink times the total molarity of NaOH will gives the moles of HCl that were neutralized.
Experimental Method Four different brands of antacids are tested in this lab. Each antacid was dissolved into 120 mL of HCl into a beaker. Using a …show more content…
Once calculated the moles of NaOH will be left. Each beaker in the experiment had a constant of 0.15 moles of HCl. The results concluded that Medi-First, active ingredient Calcium Carbonate, had neutralized the most acid in the HCl out of any other solution tested, as shown in Moles neutralized on the bar graph. It is important to note that these findings had a multitude of human errors, many of which needed to be corrected just so that the findings made any sense at all. If this was a real peer reviewed article scientist would have retested, and noticed many inconsistencies in the data, like the amount of mg in each dosage, which would have resulted in the findings to have been thrown out, and ruled
