Couple of points - Inert/recrystalisation 

Although picky I think the following sentance needs re-wording

Solvents should therefore not react chemically with the dissolved compounds — they have to be inert. I can think of several instances in which solvents also act as reagents, most notably the birch reduction (both ammonia and ethanol), formation of nucleophiles such as alkoxides, to name but a few.

An important point which should also be noted (linked) is the process of recrystalisation. dant1t
