Question 7/ Why is it necessary to cool a hot, supersaturated solution slowly during a recrystallization? Mark all that apply. Sudden cooling can cause small solid particles to come out of solution Sudden cooling in ice bath can cause precipitation instead of crystallization Sudden cooling can cause impurities to be trapped in rapidly formed crystal lattice Sudden cooling can cause more sample to come out of solution and results in higher percent recovery Question 8 During a recrystallization, which of the following will cause you to lose crystals? Mark all that apply. Dissolving sample in minimum of hot solvent Washing the crystals with minimum of cold solvent Washing the crystals with solvent at room temperature Dissolving sample in minimum of solvent at room temperature
