Imagine that you are a charge nurse in a nursing home. You are typically the only medical personnel in the house at any one time. A patient who is known to have excess stomach acid asks you to give him an antacid tablet. The typical antacid is either calcium carbonate or magnesium carbonate. The antacid tablet that you stock requires 25.82 mL of 0.200 M HCl to titrate to its equivalence point. Assume that stomach acid has a pH of 1.1. Also, suppose that the patient's size and weight indicate that his stomach will hold approximately 140 mL of stomach acid.

How many antacid tablets should you give him if you want to neutralize all his stomach acid?
Explain your rationale for your answer. Include the balanced equation you used to determine your answer.

So the nurse want to help the sick guy does she? It sounds bit fishy, but OK. You take the stomach acid and times it by the PH(140*1.1=154) so then you do the stock times the HCI.(25.82*0.200=5.164) Then take the stomach acid and subtract the stock and HCI results (154-5.164=148.836) Then you know the answer is murder. The nurse was secretly feeding the patient rat poisoning. Then she wants to "help" him. So she "doesn't" know how much acid tablets to give him so then he dies of stomach pain and rat poisoning. I hope this will help:)
