In an experiment 0.0500 M AgNO3 was used to titrate 20 mL of 0.12 M NaCl solution. When
silver electrode is used together with the pH electrode to measure potential at each point during
the titration, the potential measured at equivalence point is 0.055 V. Unfortunately, a student
doing the titration stopped at –0.055 V. Calculate the relative titration error (in percentage) of the
student’s result.
