Explain standardizes naoh titrant solution with khp

Reference no: EM13229624

A student standardizes his NaOH titrant solution with KHP. He performs three titrations - in each trial, the mass of KHP (204.22 g/mol) used is 1.500 g. The average amount of NaOH used in the standardization is 29.3 mL +/- 0.06 mL. In week 2 of the titration experiment, the student performs three titrations of 10.00 mL of Vinegar (d=1.005 g/mL) to determine the mass % Acetic Acid (60.05 g/mol), using his standardized NaOH as the titrant. The amount of NaOH used in the three trials are: 32.80 mL, 32.77 mL, and 32.84 mL. What is the concentration of the NaOH solution?

A) 0.251 M
B) 10.45 M
C) 0.0512 M
D) 0.2507 M
E) 0.735 M
