IUPUI October 12‚ 2012 Titration of Acids and Bases Introduction According to Arrhenius definition‚ acid is substance that produces H3O+ ion while base is substance that produces OH- ions. The reaction between acid and base often yields the products of salt and water. The formation of water in this neutralization reaction is caused by the combination of H3O+ and OH- ions. In order to determine the concentration of an unknown acid and base‚ a method called acid-base titration is used. The end of

The purpose of the lab was to measure the effectiveness of antacids at neutralizing excess stomach acid. A neutralization reaction is when an acid and a base react to form water and salt. To illustrate‚ H+ hydrogen ions from the acid react with the hydroxide ions OH- from the base. Antacids are taken to relieve heartburn or indigestion caused by excess stomach acid. For instance‚ antacids such as alka-seltzers contain baking soda which is highly reactive with acids‚ settling the discomfort of indigestion

Introduction Titration is a volumetric analysis technique used to find the concentration of an unknown substance. There are several types of titration but the one used for this experiment is called acid-base titration as the substance we are titrating is acidic. Acid-base titrations are based on the neutralisation reaction between the analyte and the acidic or basic titrant. The analyte is the solution of unknown concentration and the titrant is the solution of accurately known concentration used

Which Antacid Works the Best? Heartburn is a condition characterized by a burning feeling in the chest and a sour or bitter taste in the mouth. Heartburn usually develops when the acidic contents of the stomach flow back‚ or regurgitate‚ into the esophagus‚ the muscular tube that carries food from the throat to the stomach. Approximately one in ten adults experience heartburn once a week. Heartburn is more common in pregnant women because of the pressure the expanding uterus exerts on the stomach
