Formula: KHC8H4O4. If 26.37 mL of NaOH(aq) is required to titrate 0.7719g KHP to the equivalence point, what is the concentration of the NaOH(aq) (26.37 mL NaOH)(x) = (1 mol … mole = MV. Structure, properties, spectra, suppliers and links for: Potassium hydrogen phthalate, 877-24-7. - Find MSDS or SDS, a COA, data sheets and more information. Record the exact mass of KHP that you use. milliequivalent per milliliter [meq/ml],  microequivalent per milliliter [µeq/ml],  nanoequivalent per milliliter [neq/ml]  and  picoequivalent per milliliter [peq/ml]. Potassium hydrogen phthalate (abbreviated as KHP) has the molecular formula KHC8H4O4 and a molar mass of 204.22 g/mol. KHP is slightly acidic, and it is often used as a primary standard for acid-base titrations because it is solid and air-stable, making it easy to weigh accurately. All Chemistry Practice Problems Calculating Molar Mass Practice Problems. Oxygen Donor : Potassium Chlorate (only as provided in Table 3.7-1 below) KClO. **** 7) Transfer all of the KHP to a very clean Erlenmeyer flask along with approximately 100 ml of deionized water.
