B + HCl
Hello I've found this video showing reaction between boron and hydrochloric acid, and I doubt if it's possible at all. (elemental boron should be
resistant to HCl).

Please do not use google-links! Correct your post and link directly to the site with the proper URL.
I don't understand why some assume that google-links work just like static URL. They don't!

I can't see the video but it's BS: B is a metalloid and doesn't react with mineral acids. Perhaps with strong, hot nitric acid because it's a strong
oxidiser. Perhaps.

Sorry for beginners mistake. Ive already corrected it so I hope it will work.

Additional question:
I have found somewhere that when u insert NdFeB magnet into the HCl it will dissolve + u will get some boric acid - but that seems to nonsense, u
should get elemental boron instead. Am I right ?

If you dissolve an NdFeB magnet in HCl, most of the B stays behind as insoluble residue (a small amount escapes as borane/diborane). But
these magnets don't contain much boron at all.

I think B refers to an unknown compound ie compound B
not nessarily boron

If you look at his other uploads, you see he has made a series of videos of 'A + HCl', 'B + HCl', 'C + HCl', 'D + HCl' and finally 'Preparation for A
level chemistry'.
So this test tube is simply marked as item 'B' not boron 
I suspect it's zinc powder.

Boron is remarkably inert. I added crystalline boron to conc. HNO3 and heated this, but no visible reaction occurred. I could not find any aqueous
chemistry treatment, which attacked the boron at an appreciable rate. Probably with high temperature solid-solid chemistry (e.g. mixes with Mg or Al,
or mixes with strong oxidizers like KClO4) you can get it to react. Boron is nice for element collections, but for chemistry experiments it is quite
dull.

Acc. this source:
| Quote: | Reaction of boron with the halogens
Boron reacts vigorously with the halogens fluorine, F2, chlorine, Cl2, bromine, Br2 to to form the trihalides boron(III) fluoride, BF3, boron(III)
chloride, BCl3, and boron(III) bromide, BBr3 respectively. |
Wikipedia states more or less the same.
'Burning Boron' is (was?) the name of a low-grade trash metal band.

So that's really embarrasing  .
Now this topic will probably go to detritus.
Anyway thanks for answers.

If you look at the other videos on that channel, there is "A + HCl", "C + HCl", and "D + HCl" as well. So it is likely that B is supposed to mean
"unknown B" was used in the experiment, rather than elemental boron.

Yeah I know it's shame that I didn't notice it.

Well do I get an apology blogfast or are you too busy admiring your crown?

The clue was he was doing a standard school type test :does it evolve a gas in acid, color of the solution, if a gas is evolved is it CO2 or hydrogen.
The other videos are confirmation. An attached explanation of the video would have been nice.

I haven't got the foggiest idea what videos you're talking about or why others should know about them. Try and express yourself clearly in the future.

Cool, so what you're saying is, you didn't do one thread of investigation into what the title of the video could possibly mean, i.e. checking the
uploader's other videos, and then attacked someone with a low post count because they didn't agree with your conclusion. So glad we have you as one of
the main faces of this forum.

Go turn a mole heap into a mountain, Amos.
Low post count? What on Earth does that have anything to do with anything???
The video in question was inaccessible when the OP first posted it.
Seriously, I'm done here.
