WitrynaTitrating a sample of potassium acid phthalate (KHP; HKC8H4O4) with NaOH will determine the molarity of a sodium hydroxide solution (NaOH) in the first standardization. The molarity of a hydrochloric solution (HCl) will be determined using standardized NaOH in the second procedure. Witryna29 paź 2013 · PART A: Standardization of a Sodium Hydroxide solution NaOH Sample Code = O Trial 1 Mass of KHP transferred = 0.42 g Volume of Distilled water = 25 mL Volume of NaOH used = 22.50 mL Molar mass of KHP = 204.22 g/mol No. of moles of KHP = Mass of KHP used / Molar mass = 0.42 g / 204.22 g/mol = 0.0021 moles 2.
