Air-bubbles... remove them beforehand! then re-fill burette if you have to.
Read the meniscus at eye-level.
Remove the funnel before titrating.
Your 1st titration should be a rough one: allow 1 cm3 at a time, stop/ start flow method. This is to save time and know roughly around what value the end point titre should be. Remember to swirl the mixture.
For the 2nd titration add the acid in the burette dropwise to the alkali when nearing the rough titration value.
Titrate again. When you have 2 concordant values (within 0.10 cm3 of eachother) stop titrating.
There are 5 attempts max. If you don't find a concordant value by the 5th attempt, make it up!
Questions: when you run acid through the burette to 'clean it' does this mean you have to do the whole 'twirl it 360 degrees' number, or can you just let it run through into a beaker whilst it's clamped in place? Is running through the acid enough, do you have to clean it using distilled water as well?
Indicators: Methyl Orange or phenolphthalein. Do both fulfil the same role?
