During the titration of an HClO4solution with 0.10320M NaOH, a CHEM 3A student,Juan becamedistracted and overshot the endpoint. A fellow student Pedrosuggested that he should record the present volume of NaOH added and titrate the excess with a standard acid solution. If the original sample volume was 25.000mL, the volume of NaOH added was 28.060mL. It took 3.4700 mL of 0.10940 M HCl to back-titrate the NaOH andcalculate the molar concentration of the original HClO4solution.
If a titration net volume for the standardization should be 23.50 mL and a student accidentally one drop past the endpoint (~0.05 mL), will the calculated NaOH concentration (M) be higher or lower than the true value of that solution’s concentration? Explain briefly.
