1. Use the ____ and pipette filler to add 25 cm3 of alkali to a clean ____. 2. Add a few drops of ____ e.g. ____ and put the conical flask on a ____ The solution should be ____. 3. Fill the ____ with ____ and note the starting volume. 4. Slowly add the acid from the burette to the alkali in the conical flask, ____ to mix. 5. Stop adding the acid when the ____ is reached (the appropriate colour change in the indicator happens). Note the final volume reading. The ____ between the reading at the start and the final reading gives the volume of acid (or alkali) added. This volume is called the ____. 6. The first titration is a ____ titration and gives an idea of the ____ of acid needed. 7. ____ the procedure but this time when you approach the end point (about 3-5 cm3 less than the rough titration), add the acid ____ until the solution turns ____. The same method works for adding an alkali to an acid – just swap around the liquids that go into the conical flask and burette.
