If a product is highly impure (40-50% impurity), why is recrystallization not an effective purification method? Group of answer choices a-The major impurity must be incredibly similar to the desired solute; if this is not the case, it cannot co-precipitate. b-It is difficult to choose an appropriate solvent when impurities make up such a large component. c-With a large amount of impurities, not all of the crystalline material will dissolve in minimal hot solvent, forcing a hot, gravity filtration.
