A student performed a recrystallization and after the solid dissolved, the solution was immediately placed in an ice bath. Within a few seconds, a large amount of solid formed and was collected by vacuum filtration. The percent recovery was high but the melting point of the dried solid showed that the solid was contaminated with impurities. Could you explain very specifically why it happened?
