: Rinse the burette with deionized water then the acid .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 pipette to accurately measure out 25cm3 of the alkali (hydroxide). (fill to the line and read from the bottom of the meniscus), Transfer the 25cm3 of alkali into a conical flask. (Touch the surface of the liquid to get the last drop out), 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., Neutralisation is now complete. , Write down the exact volume of acid needed to neutralise all 25cm3 alkali. Reading from the bottom of the meniscus, Repeat the steps twice more., Use repeatable results to calculate the mean volume of acid required for neutralisation. ,
