Unformatted text preview: Emily Bissel March 10, 2008 Lab Partner: Becca Angell& Megan Anders MS#1116 Tuesday PM Lab 7: Potentiometric Titration Introduction By analyzing the concentrations of acids and bases, the pH or acidity can be determined for the substance. Titrations, which add an accurately measured volume of one solution to another solution can be used for this purpose. When the mole ratio found in the balanced chemical equation occurs, the reaction has reached what is known as the equivalence point. In this experiment, the substance being used, NaOH, is hygroscopic, or not available in high purity. By titrating the NaOH against KHP, the concentration of the NaOH can be standardized, or determined because the KHP is a highly pure, very stable compound available in primary standard. Using the balanced equation, one mol of NaOH reacts with 1 mol of KHP. By including an indicator or a substance which will show that the reaction has occurred, the...
