Which of the following statements is true when considering temperature during a recrystallization? More than one answer may be correct. Using ice to cool the sample will speed up the crystallization process so that large crystals will be formed. It is important that the sample is dissolved in just enough hot solvent. O Ideally the hot solvent used will keep the impurities dissolved OR not dissolve them at all. Enough cold solvent should be added to dissolve the sample BEFORE heating it past its boiling point.
