1) Rinse each piece of equipment with the solution to be placed in it (and rinse the conical flask with distilled water).
2) Using a volumetric pipette, transfer 25cm3 of the solution of unknown concentration into the conical flask. Touch the surface of the solution with the pipette to add the last drop from the pipette.
3) Add a few drops of suitable indicator to the conical flask.
4) Place a white tile underneath the conical flask to aid observations of colour change.
5) Ensure the jet space of the burette is filled with solution and any air bubbles are removed. Add the solution of known concentration from the burette, swirling the conical flask.
6) When the end point is near, add solution from the burette dropwise.
7) Note the burette reading before and after the addition of the solution of known concentration. Readings should always be to 2dp either ending in 0.00 or 0.05.
8) Repeat the titration until at least 2 concordant results are obtained (within 0.1cm3 of each other).
