Use a for the sulfuric acid.
Take the volume reading
add a few drops of to the potassium hydroxide in the flask.
add acid to potassium hydroxide until the indicator changes (use a to make the colour change more obvious).
Take the volume reading.
Calculate the rough titre using the formula:
= final volume - initial volume
Repeat the titration and add acid (near the end)
the flask to mix the solutions .
Repeat the titration until you get results (within of each other)
