Use a funnel to fill a burette with acid., Run a little acid into a waste beaker to make sure that the tip of the burette is filled., Use a volumetric pipette to accurately measure out 25cm3 of the alkali (hydroxide)., Transfer the 25cm3 of alkali into a conical flask., Add two or three drops of an indicator., Place the conical flask underneath the burette., Add acid from the burette into the conical flask, swirling the flask constantly. , Keep adding acid until the indicator just changes colour, add drop by drop near the endpoint., Neutralisation is now complete. , Write down the exact volume of acid needed to neutralise all 25cm3 alkali., Repeat the titration until you have concordant results, Use only the concordant results to calculate the mean volume of acid required for the titration..
