Sometimes a chemical reaction will produce a solid, which can precipitate from solution. But these crystals typically contain impurities from solution that were trapped in the lattice as it formed. After we isolate these crystals, we can purify them via recrystallization. This is where we dissolve them in a particular hot solvent that will then retain any impurities before cooling it down such that it can crystallize again. We will also learn how to assess the purity of our recrystallized product using melting point analysis. This is neat stuff!\n
