HML 202 Expt 25/26 Standardization of NaOH soln: Trial 1 0.4330 g 0.50 mL 22.00 mL Trial 2 0.4130 g 22.00 mL Mass of potassium hydrogen phthalate (KHP)* nitial burette reading Final burette reading Vol. used Calculate the molarities from the data and find the average value. Use the av. value to get the molarity of the weak acid, HA, You must give the correct no. of significant digits. 42.50 mL mL mL KHP = HKCsHsOa. See Expt. 20 in lab manual for method of calculation Dr. Bajue 10/24/2017
