    I was stuck on some questions from our practical:

    why do we leave the pipette to empty under gravity?
    why do we continuously swirl the flask ?
    why do we record the volume to the nearest 0.05cm^3 ?
    why do we need to rinse the beaker 2 or 3 times with small amounts rather than once with a bigger amount?
