Potassium hydrogen phthalate (KHP)concentrations can be determined through titrating samples of KHP (a monoprotic acid)with bases such as NaOH in the presence of an indicator such as phenolphthalein. The indicator is colorless in an acidic solution and turns pink in an alkaline solution. Thus, we can establish an equilibrium for the phenolphthalein with the following reaction. HIn + H₂O In⁻+ H₃O⁺ If the HIn species is "acid color" or colorless for the phenolphthalein, and the In ⁻ species is "base color" or pink for this particular indicator, what color will appear in a flask in which a 0.2993 gram sample of KHP is completely neutralized with an excess of NaOH?
