I see, an interesting paper indeed... but in the video nobody spoke about pH 7... the solution is 2 M in H2SO4 so the environment is EXTREMELY acidic. Actually, so acidic that the red precipitate is almost only V2O5 with polymeric structure. Once dissolved, the yellow species is the pervanadyl cation. Anyway, there are many "wrong" videos on the web that state that vanadate is yellow or that V(IV) is green...
Generally I do not purchase chemicals via the web. Large chemical companies do not sell to private individuals. For what I know, "United Nuclear" is one of the best web-based stores, if you live in the U.S. - I almost always rely on local retailers in my country.
For what I know the "Bayerische Defiliermarsch" is a bavarian military parade song. I was not aware of its use in such context, but it is certainly much older (1850 it seems). Anyway, no offense intended. It just sounds great!!
I do not know any compounds of V(I) but some must have been studied because "+1" is listed in the possible oxidation states. I bet they are all very unstable and hard to isolate...
+Shabista Shahid all transition metal ions with incomplete d orbitals are colourful. they all have different colours due to different d-d transition taking place in each due to difference in no. of electrons present.
@@dhanroj better to say that only transition metal ions solutions are colorful. You said "transition metals with incomplete d orbitals" when only metals with incompletely filled d orbitals are transition metals. Saiyng that you assume that group 12 elements are transition metals, when they aren't (iupac definition of transition element)
They are colored because there are d-d electron transition due to light absorbed, light not absorbed is transmitted (passes straight through the solution). The color you see is the result of the transmitted wavelenghths minus the absorbed one
Dear Sir, please note that when you copy and paste the same response to a lot of different videos you end up making yourself look foolish. The video doesn't say anything about pH 7
You are probably my favorite user on youtube. Informational, fun and exciting videos.
Omg i love this video
so clearly explained, everything well done and arranged
I think it's one of the best-done videos on UA-cam

The song is "Abandoned castle" from a Castlevania soundtrack
Great chemistry and great video editing!!!

Wonderful demonstration, very clear.
Grazie!! Questo era una cosa un po' insolita... Le idee non mancano e di video ne spunterebbero molti di più se solo avessi più tempo!!
My Little Pony somehow got me here.
you have me curious now, how even?

why do you use zinc mercury amalagm rather than zinc?
great video, also at 1:05 isn't sodium Na not S?
I love the music. Extreme chemistry!
Thank You. I love your videos. The music is always great.
Vanadium is also wonderful 😂
The equation at 2:40 is incorrect... You produce 4H20 not 6.
Yep. That's correct. Thanks for pointing it out.
awesome song, not too often where i hear castlevania curse of darkness :P
Vanadium is the coolest transition metal!!! :)
That's for sure!
really awesome, and what's the title of the music?
why is it necessary to use H2SO4 2M?
what are the control variables
So many dislikers of that lovely background music?
Great vid, love the music
which website do you buy your chemicals from? if not from a website, can you recommend one anyway?
Why use NH4VO3 to obtain V5+ ions in solution instead of reacting V2O5 solid with H2SO4?
Dude you saved me, THX!!
I do not know any compounds of V(I) but some must have been studied because "+1" is listed in the possible oxidation states. I bet they are all very unstable and hard to isolate...
Is zinc amalgam used in organic chemistry for reduction?
Why did you use so much zinc and tin?
My chemistry teacher played this at full blast, I just couldn’t man 😂
Nice video, element and music-belli video elemento e musica😂
so that means zinc amalgam doesnt react with H+ to release hydrogen?
No. This reaction is kinetically blocked because of the overpotential of Hydrogen towards Hg.
other than background music everything is great
Everything is great, the music also😂
because it does not give off hydrogen and therefore the solution does not become cloudy with tiny bubbles
a chemistry assignment vid suggestion by a teacher has led me here
Y (same)
what is the observation?
I like the music....👍
Thanks!!
lol what's with the music
Why is aqueous solution of VO2+ is colourful

What’s with the creepy music??
FInal Countdown?
Why such a horror music .... We're already scared of chemistry :|

control variables
asap
also, did you use a nazi parade song for your nitrocellulose vid (jus what google said)
