Which of the following are properties of a good recrystallization solvent? Check all correct answers. Group of answer choices boiling point of solvent < melting point of crystals boiling point of solvent > melting point of crystals Crystals are soluble in solvent at low temperature and soluble at high temperatures. Crystals are soluble in solvent at high temperatures but insoluble or slightly soluble at low temperatures. Solvent boiling point is about room temperature. Impurities should be either soluble at all temperatures or insoluble at all temperatures. An abundant amount of crystals must be recoverable from the solvent.
