The Answer is (a) Acetone is the solvent of choice because it has the lowest boiling pint and is the least toxic of the three.
(b) Ethyl acetate is the solvent of choice because it is less toxic than chloroform or methylene chloride. Ethyl acetate is sufficiently volatile that it can be removed easily from the sample.
(c) Any of these would be a reasonable choice, but ethanol would probably be the best. It is less toxic than methanol. Although ethanol is flammable, it is more vlatile than water and would be removed easily from the crystals.
