as far as I can gather you take 10 ml of isopropyl solution add 1 ml of oil shake then add a few drops of phenelphalene then count how many millilitres of tester solution you need to add.

Most seen to have moved away from titrating to using the 'two stage method'. Have a look on the wiki for that.
