Choose all of the true statements about the process of recrystallization. o recrystallization is used to purify liquid compounds. o recrystallization is used to purify solid compounds. o activated charcoal may be used during recrystallization to assist in removing some impurities. o a supersaturated solution can be induced to form crystals by "seeding" with a small crystal of the original solid product. o a good solvent for recrystallization will dissolve a large amount of the desired substance when hot, but a very small amount when cool. o crystallization can be induced in a supersaturated solution by scratching the side of a beaker after a solution is cool. small crystals are less likely to absorb impurities because they have a much smaller surface area than large crystals.
