Cell Biology Laboratory 4: Essential Laboratory Skills
Read everything and then ONLY answer the following questions:
1) Discuss the results of your experiment. Describe the effectiveness of Tums in neutralizing the acid in this experiment.
2) How much NaOH was required to neutralize the acid remaining after the antacid was absorbed?
3) How much stomach acid does the antacid neutralize? Calculate your answer expressed in mL of stomach acid neutralized per gram of antacid (mL acid/g antacid).
4) How much NaOH would have been required to neutralize the original 75 mL of HCl? Acid BaseM1V1 = M2V2
5) The molarity of the HCl in gastric acid is 0.16M. With this information, what volume of stomach acid can be neutralized by the Tums used in this experiment?
