Consider an 50.0 mL analyte solution containing 0.50 g of KHP, titrated against 0.10 M sodium hydroxide, NaOH (a) Based on the information you have for the hydrogen phthalate ion HP– and the fact that Kw = 1.0 × 10−14 at room temperature, what is the Kb of the phthalate ion P2–? Write the chemical equation that has a Kc equal to Kb you just calculated. (b) What is the pH of the solution at the equivalence point at room temperature? (c) Sketch the beaker again at 50% past the equivalence point. What is the pH of the solution at room temperature?
