What does the term bumping mean in chemistry?

In: Organic Chemistry [Edit categories]

Answer:

Bumping is a process in which a solvent becomes superheated and then undergoes a sudden release of a large vapor bubble, explosively forcing liquid outside of a flask.

You may have tried using boiling chips in organic chemistry lab during a distillation experiment. Boiling chips are made of a porous material and have a nonreactive Teflon coating - they provide nucleation sites (extremely localized budding for gaseous bubbles) so the liquid boils smoothly/more easily. The air bubbles break the surface tension of the liquid being heated and prevent superheating and bumping.

An ebulliator can also be lowered into a distillation flask to introduce small air bubbles - this serves the same function as boiling chips.
