CHY 123 Antacid Analysis: A Back-Titration Introduction One of the most common medical issues plaguing Americans today is G.E.R.D (gastroesophageal reflux disease). This is caused by special cells in the stomach that excrete acids into the stomach to help in digestion; however, these acids are excreted in larger then needed amounts and find their way to the esophagus where they splash up and can cause severe damage over time. Antacids are basic tablets that help to neutralize the acids and make people more comfortable. They work by countering the acids in the stomach until a better ratio is found. Procedures We gathered the needed chemicals and containers needed for the experiment. We set up two burets so that we could add HCL or NaOH to the beaker. We then filled one beaker with a crushed antacid tablet and 100ml of distilled water. We heated the solution a little to make sure the tablet was dissolved even after we had crushed in the mortar with the pestle. We then added 10 drops of the Methyl Red indicator solution. We then added 35ml of the HCl
