The purpose of today’s lab was to determine how effective antacids are at neutralizing HCl. This experiment required us to place 3 antacids tablets into 3 Erlenmeyer flasks. Next we were required to add 50.00 mL of 0.500M HCl and five drops of phenolphthalein. Finally, we needed to titrate NaOH into the flasks. Each antacid brand required a different amount of NaOH in order for it to be completely titrated. The data collected from the experiment allowed each group to calculate the cost effectiveness of each brand of antacid. To do so we were required to calculate how many moles of HCl were neutralized by one antacid tablet. Next we were required to calculate how many moles could be neutralized by one bottle of a certain antacid; to do this
