INTRODUCCIÓN

Los productos sólidos que se obtienen en una reacción suelen estar acompañados
de impurezas que hay que eliminar para poder disponer del producto deseado en el
mayor grado de pureza posible. El método más adecuado para la eliminación de las
impureza que contamina un sólido es por cristalizaciones sucesivas bien en un
disolvente puro, o bien en una mezcla de disolventes. Al procedimiento se le da el
nombre genérico de recristalización.

El sólido que se purifica se disuelve en solvente caliente, generalmente a
temperatura de ebullición, la mezcla caliente se filtra para eliminar todas las
impurezas insolubles, y entonces la solución se deja enfriar para que se produzca la
cristalización de la sal. En el caso ideal, toda la sustancia deseada debe separarse
