Fluorine (version 1)
Fluorine (version 1) - Periodic Table of Videos
Introduction
In this video from the Periodic Table of Videos, the presenter discusses the highly reactive element fluorine, its properties, and its applications. Fluorine is known for its extreme reactivity and hazardous nature.
Main Points
Reactivity and Properties
- Extreme Reactivity: Fluorine is the most reactive element on the periodic table. Its reactivity makes it dangerous to handle and requires special precautions.
- Appearance and Smell: Fluorine is supposed to be pale green, but the presenter has never seen or smelled it. Fluorine reacts with the water in the nose to produce hydrogen fluoride, which smells dreadful and is highly corrosive.
Hydrogen Fluoride
- Corrosive Nature: Hydrogen fluoride (HF) is incredibly reactive and can dissolve human flesh. This makes it a significant hazard in any laboratory setting.
- Personal Anecdote: The presenter shares a story about reading "The Wizard of Oz" to his son, who humorously asked if the water that melted the Wicked Witch contained HF.
Special Procedures
- Apparatus for Fluorine Reactions: The presenter shows a unique piece of apparatus used to make oxides of fluorine (O2F2). Fluorine and oxygen gases were passed through the apparatus, and a high voltage was applied to dissociate the molecules and allow them to react.
- Cooling with Liquid Nitrogen: The apparatus was immersed in liquid nitrogen to freeze the product, O2F2, on the walls of the vessel. This setup highlights the extreme conditions needed to safely conduct reactions involving fluorine.
Conclusion
Fluorine's extreme reactivity and hazardous nature require special handling and equipment. Its ability to form highly reactive and corrosive compounds, such as hydrogen fluoride, makes it both fascinating and dangerous.
