I wondering how to dry a solvent. I looked it up and found out a bit but I always seem to learn more from you guys so if you have a few ways to dry a solvent or even other things feel free to drop them on my head...

I know of one that I learned on you tube which is pretty cool... You seal a cup of sodium hydroxide and the cup holding what your trying to dry in a bag like an oil that has a little water in it...
There are different methods for different solvent what you intend to dry.take absolute ethnol for example,generally speaking,we use magnesium to dry ethnol,reflux magnesium and ethol for 1h in a round bottom flask,iodine as initiator,and then distill the ethnol.
