The purpose of this lab is to determine the concentration of citric acid in common beverages by using the technique of titration. Citric acid is a weak acid. A weak acid-strong base titration will be performed in this lab. The titrant is sodium hydroxide. The strong base is titrated into various beverages that contain citric acid. There are two titration methods in this lab. Prior to the formal lab, the introductory activity is placed to help decide the most appropriate indicator to use in the performance of a weak acid-strong base titration. The introductory activity is also performed to determine the exact molarity of the titrant. In order to complete titration, the molarity of the titrant must be known. For the formal lab, the first method
