joannek Posted March 31, 2010 Posted March 31, 2010 Why is an hot ethanol/hot water solvent good for recrystallizing benzoic acid?
Horza2002 Posted March 31, 2010 Posted March 31, 2010 When the mixture is hot, benzoic acid will dissolve in it. Once it begins to cool down though, it'l get to a point where it is insoluble in the mixture and so will crystalise out
