I have to answer some questions regarding the titration practical which I have really no clue how to answer:
why do we make a solution of a similar concentration as the unknown one?
why do we need to rinse the beaker two or three times with small amounts rather than once with a bigger amount)?
why do we pipette the solution from a beaker rather than directly from the volumetric flask?
Why do we leave the pipette to empty under gravity?
any help is appreciated!
