Hello guys! As I told you, in this video I’m gonna show you
chemical reactions with Sulfur hexafluoride,
‘cause, you know, everyone only does deep voice
or aluminium foil ships with it, no chemistry, so I’m gonna do it
Sulfur hexafluoride is very
chemically inert gas, it doesn’t interact
with anything at a room temperature,
so to make it react we’ll need high temperature,
and the easiest way
to get high temperature is to burn metal.
Lithium’s burning temperature is about 1300,
degrees Celsius, and the tempertature of
lithium’s reaction with Sulfur hexafluoride
is more than 2500 degrees
So let’s do this reaction, and by the way, it was suggested in comments by one of the subscribers
Before I show you the reaction, I’d like to
demonstrate how lithium burns on it own, it’s nice
and maybe you’ve never seen it before
to show you the reaction of lithium and Sulfur hexafluoride,
I filled this litre flask with the gas
and put a small burning piece of lithium
But I wasn’t quite satisfied with this reaction,
so I decided to turn this Sulfur hexafluoride jet
from the gas cylinder to the burning lithium
Simply put, metal reactions are based on the fact
that Sulfur hexafluoride decomposes into elements
at the temperature higher than 800 degrees Celsius,
so the products of metal reactions
are always sulphides and fluorides of metals
So, if I make excess gas you can see unreacted
sulphur resulted from reaction
Sulphur hexafluoride (SF6) is often used as a ‘cover gas’
during magnesium smelting,
to prevent the molten magnesium from reacting with oxygen.
But if your magnesium ignites, this cover will turn into weakness
in a science article I read that titanium reaction
is also violent, so I did it too
I also did this reaction using other alkaline earth metals
Now you’re gonna see a really beautiful combustion
reaction of strontium, I enjoyed it more than lithium burning
I also had some metallic Samarium, and, knowing
how active it is, I decided to use it for a reaction
For those who have no idea, samarium powder is
extremely flammable, even pretty big shavings
of it will ignite from a cigarette or smoldering wood
Thanks for watching it up to the end, so, the last thing
I wanna show you is a really
fascinating reaction with lithium and solid
Sulfur hexafluoride
it’s melting point is -64°C
so it’s not very hard to freeze it and then use
by the way, just like dry ice, Sulfur hexafluoride sublimates,
meaning it goes from solid to gas state without transition to liquid
in this picture that I did you can notice
Orthorhombic Crystal structure
so it’s time for the lithium reaction

make the channel popular, and
the increase in subscribers is in direct ratio
to the increase of my inspiration for new exotic chemical reactions
