Heartburn and “Aunty Acid”IntroductionWhen consuming too much food or drinks, we might experience aheartburn. Gastric acid contains hydrochloric acid, sodium chloride, andpotassium chloride. The digestive system plays an important role in our digestionof proteins which activates the digestive enzymes In this lab, we learned aboutheartburns and how it’s caused by excess acid; HCI which can lead to ulcers inthe stomach lining. We will be taking three different brands of antacids: Tums,Alcalak, and Alka-Seltzer. My partner and I, did an experiment on Tums and wecombined it with 0.1M HCI. Titration is a big part of our experiment, a techniqueto add reagents. We will be seeing how effective antacids help neutralize stomachacids. We will be titrate the solution with the strong base sodium hydroxide. Thepoint of this lab to figure out with antacid which cost is efficient and massefficient.MaterialLab ManualLab NotebookPenWax pencilCalculatorGooglesTums, Alka-Seltzer, and AlcalakMortarPestleWeighing paper250 mL Erlenmeyer Flask0.1M Hydrochloric acidHot PlateBuretteRing standBurette HolderPhenolphthalein indicatorGraduated Cylinder
