Boiling chips, also known together boiling stones, boileezers or anti-bumping granules, room small, irregularly shame stones added to liquids to do them boil much more smoothly. They carry out nucleation sites therefore the fluid boils quickly without becoming superheated. Without boiling chips, a fluid heated in a smooth container can become superheated and also release vapor suddenly, sometimes violently. This sudden bubble of gas can reason the solution and also reagents to be thrown the end of the container, possibly resulting in severe burns, destroying an experiment, or just making a mess.
Boiling chips are typically made that a porous material, such together alumina, calcium carbonate or carbon, and also often have a nonreactive coating the PTFE (Teflon). This ensures the the boiling chips will provide effective nucleation sites, yet space chemically inert. In institution laboratories, piece of damaged ceramic crucibles are regularly used.
You are watching: What is the purpose of boiling chips
Boiling chips need to not be included to liquid the is already near its boil point, as it could cause a large amount of vapor to type all at once. This could cause hot liquid to it is in expelled native the container, maybe causing warmth or chemistry burns.
