A brief intro to the lanthanides (5/8)

[lexichronicle2]

no where near enough views considering how many people on here claim to be interested in chemistry - and not just in it for the hazmat suits

[AndromedaChao2]

What about the radioactive lanthanide promethium? Can that form a tripositive ion solution also if it is dissolved and oxidised?

DRINK IT!! xD

1:41 crack? xP jk btw

@iVoltTV Cerium 4 not even remotely funny

OUlearn:

1) Beautiful video.

2) I love chemistry :), and I was wondering: would you purify the lanthanide chlorides by ehating them and driving the water away?

3) The video says that Ce(IV) is reduced to Ce(III). Does this means that Ce(III) sulfate forms?

@JonathanTheAlchemist

2) Heating dries the sample, but isn't a method of purification. Sinse is was made by disolving pure metal in pure acid it needs no purification.

3) yes. that is what reduction means.

[JesusHChrist2000]

Hydrogen peroxide as a reducer??

[JavAnarkoMet]

@JesusHChrist2000

just somtimes, more of the times is oxidizer

[derkozten]

@JesusHChrist2000 of course. H2O2 can act as a reducer as well as an oxidant, depending on what is reacting with peroxide. When it acts as a reducing agent, it forms O2 gas as the oxidized product. For example, it can reduce permangante [MnO4(-)]

[randomenvelope]

this made me wanting sprite so bad.

[fsadfvewb]

Lutetium is also a lanthanoide.

[mrinvisible88]

what you have as "is involved" in the subtitles is supposed to be "is evolved"

[OUlearn]

Thanks, fixed.

[giantmousesdontexist]

this is a beautiful video

[pspgamecrazyfan]

huh

[douro20]

Promethium is radioactive.
