1) Use a pipette to measure sodium hydroxide solution
2) Pour it into a conical flask
3) Add a few drops of phenolpthalein
4) Pour hydrochloric acid into a burette. Read the scale
5) Add hydrochloric acid from the burette to the conical flask until the indicator turns colourless. Swirl.
6) Read the scale. Calculate the amount of acid added- gives an idea of how much acid is needed to neutralise the sodium hydroxide
7) Repeat the steps until you have 3 consistent values for the acid volume
