Why is potassium hydrogen phthalate a good primary standard
Asked by maham237 @ in Chemistry viewed by 283 People
A solution of the primary standard potassium hydrogen phthalate (KHP), KHC8H4O4 , was prepared by dissolving 0.4877 g of KHP in about 50 mL of water. Titration of the KHP solution with a KOH solution of unknown concentration required 26.12 mL to reach a phenolphthalein end point. What is the concentration of the KOH solution?
