hey guys this channel has already reached 10,000 subscribers and something
tells me that this year we'll see really cool chemical reactions and today I will
show you the reaction of a sodium-potassium alloy with bromine or
maybe with something else
So, let's prepare sodium-potassium alloy by fusing potassium and sodium in hot vasilin oil
on a approximately three to one mass ratio.
This large drop of the formed alloy can be divided like mercury into many small drops
that will then merge to form a large drop
look at this squeaky clean, non-oxidized alloy surface
So, it's time to start our experiment! Let's draw up some liquid metal into a syringe
Yes, it really is a liquid that freely passes through the syringe needle
Sodium-potassium alloy is much more active than potassium,
and therefore, literally a few minutes later, the oxidation products of the alloy
harden inside the needle so nothing can pass through it anymore.
So let's perform our experiment real quick
Before our main reaction with bromine, let's warm up and drop this alloy into a solution of perchloric acid
Yeaaah, I expected a much more active reaction ... Well at least it would be awesome with bromine, for sure!
So guys, we have bromine vapor in a glass box
and this is a great opportunity to show you
how much heavier sulfur hexafluoride gas will push these vapors out of it
Thanks for watching guys, like the video, comment and subscribe,
and I’m leaving to shoot a new video,
because there are already ten thousand of you, so I need to post new videos more often!
Seeya next video!
