Potassium hydrogen phthalate, known as KHP (molar mass 5
Chapter 8, Problem 8.149(choose chapter or problem)
Potassium hydrogen phthalate, known as KHP (molar mass 5 204.22 g/mol), can be obtained in high purity and is used to determine the concentration of solutions of strong bases by the reaction HP2(aq) 1 OH2(aq) 88n H2O(l) 1 P22(aq) If a typical titration experiment begins with approximately 0.5 g of KHP and has a final volume of about 100 mL, what is an appropriate indicator to use? The pKa for HP2 is 5.51
