    I'm preparing an iron (II) ethandioate complex.


    One of the steps is to filter the iron (II) ethanedioate under reduced pressure. (using tap).


    I understand what to do, but I was wondering if you could give me some tips so I can get the solid AS DRY AS POSSIBLE!?


    Thanks ;D

    Not an experienced chemist, but would using a drying agent (eg anhydrous copper sulphate, or similar) help?

    Thanks! I found out we'll be using propanone as the 'wash'.
    Do you leave the tap on while you're washing it by the way?

    Leave under vacuum for 20 minutes if you're using a Buchner. For some complexes, you can use ethanol or some other solvent to dry better, but it really depends on the complex. Also I tend to put my palm on the Buchner to put some pressure on it which my lecturers hate, but its to close the system as much as I can; people say this doesn't work but it really does!!!

    Chemistry labs are so tedious it's untrue.
