Light Bulb in Hydrofluoric Acid (HF)
We dunk a glowing lightbulb in HF - an acid famed for being disagreeable with glass. Discuss on Brady's subreddit: http://redd.it/2mrnyw More chemistry at http://www.periodicvideos.com/ Follow...

HF - hydrofluoric acid is probably the most feared chemical compound that there is. The reason it's so feared is that is that it is very corrosive. It will burn through human skin. Even quite a small exposure on your skin can cause a heart attack. And I really wanted--and I still want--to do an experiment with HF. ... or rather, I want Neil to do an experiment for me with HF. I want to see what happens if we put a lightbulb--an electric lightbulb--the old, not energy saving sort into a beaker of HF. The reason why it's interesting is because HF can dissolve glass. Glass, the chemist's friend: we use it for test tubes, bottles, Kipp's Apparatus but HF attacks glass. Chemically, it breaks the silicon-oxygen bonds and forms silicon-fluorine bo...
