I need step by step procedure (pleases write a
procedure as to how you will perform your separation) --This should
be written up in sufficient detail so that another student in
Chemistry could follow it to separate and purify your mixture. Be
sure to include details as to how much solvent is used,
concentration of acids and bases, temperatures of any
processes.
