The main foods and beverages that cause heartburn include spicy food, fatty foods, acidic foods and beverages, and alcohol. The consumption of these foods can cause the lower esophageal sphincter to relax, or it may promote the creation of excessive stomach acid (FACEP). The normal pH of the esophagus is around 7 (Tutuian), and the pH of stomach acid is between 1.5 and 3.5 (“Stomach acid test.”). The pH of the esophagus shifts to 4 when acid reflux occurs meaning that it became more acidic. The acid in the stomach is important for digestion and for the immune system. The acid helps break up food and proteins, while protecting the body from any germs and bacteria that are in foods or liquids consumed. The acid also promotes and supports an intestinal…show more content…
A titration is the precise addition of a solution from a buret into an accurately measured volume of a sample solution. A titrant is the solution in the buret that is used for the titration, and the volume of the solution is known. The titrants used in this lab were 0.1M hydrochloric acid and 0.1M sodium hydroxide (the reactions can be seen in figure 4). A Bronsted-Lowry acid is a compound that donates a proton. A Bronsted-Lowry base is a compound that accepts a proton. A conjugate acid-base pair is a pair of substances in a reaction whose molecular formulas differ by a single proton. An indicator was used to indicate when to stop the titration, an indicator is compound that is added in small amounts to indicate the pH of a solution visually. The indicator used in this lab was methyl orange. This indicator is pink/red when a solution is acidic, orange when it is neutral, and yellow when basic…show more content…
The prices for a bottle may vary due to various reasons such as strength, brand names, or even the consistency, such as tablets or gummies. The problem here is that there are so many types of antacids at a variety of prices however, how effective the tablets are tends to be unknown. Due to this, the purpose of this lab is to assist consumers in deciding which type of antacids to buy based on the cost and how effective the tablets are at neutralizing the acid found in the stomach. This will be found by performing two different titrations where the antacid will first be reacted with hydrochloric acid and then this will be reacted with sodium hydroxide. It is hypothesized that the Life Brand bottle of antacids will be the most cost-effective because it is the cheapest bottle and it claims to have the same amount of tablets as the Tums Regular Strength with the same amount of calcium carbonate per tablet as the
