Question

macmilan learning While performing a recrystallization, a chemist notices that a small amount of the sample will not dissolve, even after the recrystallization solution has been boiling for some time. Select the correct course of action. O Perform a gravity filtration with a stemless funnel. o Cool the recrystallization solution to room temperature and then O Perform a gravity filtration with a long-stemmed funnel. heat it again to dissolve the insoluble material. Isolate the insoluble material via filtration, grind it into a powder, and add it back to the recrystallization solution

Explanation / Answer

Answer:

In recrystallization process, Flute a piece of filter paper and place it inside of a stemless funnel. A funnel with a stem is prone to premature recrystallization inside the stem because the filtrate can cool as it passes through the stem. At these cooler temperatures, crystals are likely to form.

Option-1 is correct
