Das Cobaltsulfat reagiert mit dem Hydroxid zu Co-Hydroxid ausgefällt, anschließend aber wieder vom Nh3 zum Cobalt-Hexamin-komplex gelöst, der rot ist. Richtig?

@sursrain it`s a magnetic stir bar (a little magnet driven by another [rotating] magnet under the erlenmeyer)

whts that lil thing spinnning in the erlenmeyer?

NH3 prefers to be in the gas phase

YOU CAN MAKE IT WITH CUPPER ROD IN NH3 ELECTROLYSIS

Copper(II) hydroxide redissolve in excess ammonium

we usually say [Cu(NH3)4]2+ instead of [Cu(NH3)4(H2O)2]2+ because the 2 H2O is so loosely held(u may check the bond length, it is fairly long). hence, we dont assume the two H2O is coordinated to the copper

Mimi Zhang commented on 19 May 2013

DId you mean [Cu(H2O)6]2+ + 4NH3 = [Cu(NH3)4(H2O)2]2+ + 4H2O

hkchem commented on 16 Oct 2013

just four ammonia coordinate to the copper(II) ion

hasjfa commented on 04 Oct 2013

[Cu(NH3)4]2+ where does the 4 come from

RadioTrefoil commented on 17 Jun 2012

*ammonia, ammonium is an ion NH4.

hi ...wanted to ask that shouldn't i use normal h2o2 from a chemist of about 5% concentration .....would it work?

Игорь Ковальчук commented on 10 Oct 2012

Hi, no you need concentration at about 30% minimum, try to find it ot make it:)

Игорь Ковальчук commented on 28 May 2012

Hydrogen peroxide was about 35-40 %, i made it from Carbamide peroxide pills.

John Upperman commented on 27 May 2012

can you please tell me what percentage and grade the hydrogen peroxide is?

Игорь Ковальчук commented on 25 Aug 2011

@Uatarreu Yes, the song is Moonbeam - Slow Heart. Thank you for watching!

Uatarreu commented on 24 Aug 2011

could you tell me the name of this song?? i really love it... thanks

Nick Romero commented on 19 Aug 2012

I can't seem to find us at CVS/Pharmacy. Where did you get it?

Игорь Ковальчук commented on 14 Oct 2012

sorry, i do not understand your question?

charleville13 commented on 17 Jan 2012

I wish you would continue to make these!

Udit Vaish commented on 14 Oct 2012

whats the chemistry behind this?

mailnotwanted commented on 14 May 2012

it is like the flask ejaculating

Nick Romero commented on 22 Jul 2012

Where did you get the KMnO4 ?

andy johnson commented on 16 Sep 2012

wat is the stuff u put in it

juneace98 commented on 10 Mar 2013
