Part 4: 4. Acid reflux is caused when stomach acid enters the food pipe. When we eat food, it goes through food pipe, also known as esophagus, and enters our stomach. Stomach acid helps in the digestion of food. When stomach contents, including stomach acid, leak backwards into the food pipe, it causes acid reflux, which is also known as gastroesophageal reflux disease (GERD). Stomach acid, also called gastric acid, is a digestive fluid formed in the stomach. This acidic fluid is composed of hydrochloric acid with large quantities of potassium chloride and sodium chloride. The stomach acid has a pH of 1 to 2. Nprmal Backflow of acid Q and stomach contents into the esophagus To prevent acid reflux, some food and beverages may be avoided. These include alcohol, caffeine, chocolate, tomatoes and spicy foods. Excess meals may cause production of excessive stomach acid increasing the chance of acid reflux, so small meals are recommended. Over-the- counter antacids may be used after meals and at bedtime. An example of an antacid is magnesium oxide. Magnesium Oxide 400 m y Bupplement VIR a. Show the balanced chemical reaction between stomach acid (hydrochloric acid) and the antacid, magnesium oxide. (Hint!: one of the products formed in this reaction is water). b. State the names of the products that are produced from this reaction. Is the reaction in part (a) an acid-base reaction? с. d. If this is an acid-base reaction, then identify the following: acid (formula and name) that is reacted base (formula and name) that is reacted salt (formula and name) that is formed e. What is another typical, everyday name for an acid-base reaction? f. If this is also an oxidation-reduction (redox) and/or precipitation reaction, then show work to support your answer. If this is not an oxidation-reduction (redox) and/or precipitation reaction, then show work to support your answer. g. If the pH of stomach acid is 2.0, calculate the H* ion concentration. h. What is the pH of a solution with a hydronium ion concentration of 0.005 M? i. Is the solution in part (h) acidic, basic, or neutral? ||
