Boiling chips, also known together boiling stones, boileezers or anti-bumping granules, are small, irregularly shaped stones included to liquids to make them boil much more smoothly. They carry out nucleation sites so the fluid boils easily without coming to be superheated. There is no boiling chips, a liquid heated in a smooth container can end up being superheated and release vapor suddenly, sometimes violently. This sudden bubble that gas can cause the solution and also reagents to be thrown out of the container, possibly resulting in severe burns, ruining an experiment, or simply making a mess.

Boiling chips are frequently made that a porous material, such together alumina, calcium lead carbonate or carbon, and often have actually a nonreactive coating the PTFE (Teflon). This ensures the the cook chips will administer effective nucleation sites, yet are chemically inert. In school laboratories, piece of broken ceramic crucibles are frequently used.

You are watching: What is the purpose of boiling chips

Boiling chips have to not be added to liquid the is currently near its boiling point, together it could cause a huge amount the vapor to form all at once. This could cause hot liquid to be expelled indigenous the container, perhaps causing warmth or chemistry burns.
