a student dissolves 0.625 g of pure benzoic acid in distilled water and titrated the resulting solution to the equivalence point using 40.8 mL of the standardized NaOH solution from Part a, assuming that benzoic acid has only one ionizable hydrogen, answer the following: writing the unknown formula of benzoic acid as HA, where H is the ionizable hydrogen atom, write the balanced molecular equation that occurs in this titration.. Part A: the student begins by standardizing a solution of NaOH. he uses potassium hydrogen phthalate, KHC8H4O4 (MM=204.22 g/mol), a monoprotic acid which reacts with NaOH as shown in the following balanced equation: KHP + NaOH = H2O =KNaP
