The following data were collected during the titration of a solid sample of potassium acid phthalate ("KHP") with a solution of sodium hydroxide. The NaOH solution was added to the KHP from a buret. From the experiment data below, calculate the molarity of the NaOH solution. Data: Molar Mass of potassium acid phthalate= 204.23g/mol Mass of weighing bottle plus KHP= 23.4061 mL Mass of weighing bottle= 22.0515 g Initial buret reading= 0.20 mL Final buret reading= 39.13 mL

1. A solution of sodium hydroxide (NaOH) was standardized against potassium hydrogen phthalate (KHP). A known mass of KHP was titrated with the NaOH solution until a light pink color appeared using phenolpthalein indicator. Using the volume of NaOH required to neutralize KHP and the number of moles of KHP titrated, the concentration of the NaOH solution was calculated. Molecular formula of Potassium hydrogen phthalate: HKC8H404 Mass of KHP used for standardization (g) 0.5306 Volume of NaOH required to neutralize...
