Acid in your Stomach

\

PH Lab Concepts:

During this lab we learned that Antacids are medicines that work by increasing the pH balance in your stomach. A lot of antacids can quickly take care of symptoms like heartburn and indigestion. Antacids are able to make you feel better by increasing the pH balance in your stomach. 


The pH system is a scale for measuring the acidity or alkalinity in your stomach. The scale goes from 0 to 14. A pH of 7 is neutral, below 7 is acid, and above 7 is an alkaline. In order for an antacid to actually act fast, it has to get up to 3 or 4 just so it can handle everything happening in your stomach. 

We tested all of these products and the Tums® can out to be a 5, which was really good. In the vinager it bubbled and fizzed, then flatened out. It showed us how powerful it components really were. The Rolaids® stayed at a 3 on the pH level. It foamed up, and remained like that. It wasn't as potent as the Tum obviously. We also tested two different types of Antacid Tablets. Both remarkably had a pH level of 5, but only one fizzled like the Tums®, while the other had no reaction and just mix with the water, it just kind of floated around. Either way, all of these products were made to balance out the pH in your stomach. Some products may be thought to work faster and better because of the brand, but in the end they are all created for the user and each had almost an equal amount in pH levels.
