Neutralizing Stomach Acid Experiments

Jul 11, 2017. Antacids do just what their name suggests: they neutralize the normal stomach acid (HCl), causing the pH to rise to a nearly neutral pH of around 6 to 7. As the pH rises above 4, pepsin activity decreases or stops. Some types of antacids, made of sodium bicarbonate (NaHCO3) or calcium carbonate.

In today's experiment you will be studying energy exchange (exo/endothermic), and the effect of temperature and surface area on the rate of reaction. You will be. The sodium citrate is a buffer (meaning it is resistant to change in pH), and it can neutralize stomach acid HCl (Hydrochloric acid) by the following reaction:.
