Question:

Name the functional acidic groups of Alka Seltzer and their pKa values.

Antacids:

Antacids are over-the-counter (OTC) medications used in neutralizing the acids in the stomach. These drugs reduce the secretion of acid in the stomach.

Stomach pH:

  • The pH of human stomachs is carefully regulated in order to enable us to digest food, and to protect us from bacterial infections.
  • The very low pH of the stomach is produced by parietal cells of the stomach, which pump protons and chloride ions into the stomach to produce hydrochloric acid.
  • Sometimes the acid in the stomach can be forced out into the esophagus, producing the painful sensation of heartburn.
