To each flask, add 100 mL of acetic acid solution measured accurately with pipet.
Suggested initial concentrations are. Using 100 mL volumetric flasks, prepare the
following acetic acid solutions – 0.30, 0.27, 0.24, 0.21, 0.18 and 0.15 M – by
adding the respective quantity of 0.30 M acetic acid stock solution (see chart
below) and make up to the mark using de-ionised water:
