Unformatted text preview: OH- ions, accepts protons, and donates electron pairs. Materials and Methods In this experiment, the various methods of determining the pH of a solution are compared. A secondary standard, NaOH will be standardized with a primary standard potassium hydrogen phthalate, KHP. After the NaOH solution is standardized, using a phenolphthalein indicator and a stir bar until the solution turns pink, titrations of NaOH with hydrochloric acid then with acetic acid are performed. Potentiometric titration of polyprotic acid with phosphoric acid and the determination of acid content in yellow mustard trials are performed. Results and Discussion Conclusion...
