Describe how to use the apparatus to do titration using 25cm-cubed of dilute hydrochloric acid.
Use the pipette and pipette filler to add 25 cm3 of alkali to a clean conical flask. Add a few drops of indicator and put the conical flask on a white tile (so you can see the colour of the indicator more easily). Fill the burette with acid and not
