- Given the following experimental data, calculate the molarity and the pK of the acid
analyte (HA) in the titration, if the balance neutralization reaction is:
HA+ NaOH NaA + H2O.
A pH reading of 3.65 was obtained when 13.0 mL of 0.413 M NaOH was added to
the 25.0 mL analyte.
The endpoint was achieved when 31.25 mL of NaOH had been added.
