Neutralization of Stomach Acid in our Chemistry Class

My students need six pH probes to investigate what the pH of stomach acid (HCl) is and what happens to the pH when you neutralize it with an antacid.

My Students

Students learn science best by doing. I like to set up experiences that have real world applications. The focus in education is to have students learn by discovery or inquiry where they are given a problem and asked to come up with answers.

I teach high school students who have a high interest in chemistry.

They are high achievers with aspirations to study science in college. Many of them will become doctors, pharmacists, engineers, and work in other science and medical related fields.

My Project

I have requested six pH probes so my students can investigate what the pH of stomach acid (HCl) is and what happens to the pH when you neutralize it with an antacid. My students will use these pH probes to do investigative work with acid and base neutralization. They will measure the pH of hydrochloric acid in our lab. They they will add variable amount of baking soda until the pH has increased to 7 at which point the acid has been neutralized.

Students will have some idea about stomach acid and what health problems can occur with excess amounts of acid.

They will learn how antacids work to neutralize the stomach acid and eliminate some of the health problems.
