Green Flames with Copper (II) Oxide

[demnlordd666]

so I made Cu(OH)2 via electrolysis and decomposed it with heat to CuO ( Cu(OH)2 --> CuO + H2O ) but when I added methanol and lit it it had trouble turning the flame green. only when it burnt down to the black dust it was green. did you leave yours in the solution for a while or did it work right away? My oxide might be impure but not too bad. suggestions?

[GlitchesUploaded]

HEY MATE IVE GOT SOME COPPER (II) OXIDE BUT HOW DO YOU USE IT PLZ REPLY. AN WATS DAT STUFF YE SPRAYIN ON ?

[hydriodic]

Who cares if it backfrafts they're grown leave them alone

[KarikoEmpire34]

I have the best science teacher ever! We burned Copper Oxide in class as well as other things like Calcium Chloride, Potassium Chloride, etc. Flamebow!

[YooEssBee1]

thats slightly dangerous what if it back drafts back into the spray

[SolitudeInDarkPlaces]

FLOO POWDER POWER

[YooEssBee1]

does this work for copper (III) Oxide

[TheMrbunGee]

methanol is toxic and it doesnt disolve CuO.

what you have there is boric acid and ethanol ;)

And CuO gives blue flame.. ;)

[havensoldier34]

DIAGON ALLEY!!!

[luciankevi123]

it's like the harry potter flames!

[veverel93]

bay nu mai vorbiti engleza, gata de acum vorbiti si voi ca oamenii

[gummyform]

so thats what was in the powder for harry potter and the chamber of secrets!

[dalesalsa]

Chemistry is fuckin sweeeet... :-D

[SpyderRyder3600]

*dips finger in* DIAGON ALLEY!

[Heliman96]

Lol you just lit it in a spoon

[drfreezepop]

HAVE A BATCH of this STUFF!

can wait till it dries ouT!

[ilijacar3]

more cmon burn the whole house up!!!!!

[mkeany010]

@ItchyNipple13 or.. were just retards who didnt pay attention in chemistry :P

[bapyou]

Jesus. You should get a job working on a David Lynch movie.

[alvon999]

base + acid = water + salt ..~

[11to]

can you do it in etanol?

[Scraleontis]

yeh but you wont see the green flame as clearly as in methanol. Try dissolving Bori Acid in Methanol, that will give u a pure green flame.

[antiswattt]

YES!!!! i got some very nasty food :( with chopped pork pieces in.. in the bottom of my dish theres floating fat.... damn do i have to be muslim for that my mom will never give me this kind of food

[antiswattt]

or just glock 18 to the head and pull the trigger, burn corpse and file down wheelchair xD it always wprks, just remember to powder the bones and dig into a hole with acid

[antiswattt]

hehe >=) will do when i find one with a wheel chair

[antiswattt]

well my chemical teacher or watever its in english says (them both) that some glasses (the metal part) is made of titanium

[antiswattt]

bwaarrrr qx ive heard that some glasses (the metal part) is made of titanium... (: so im trying to get some glasses and then hope its made of titanium hehe do you know anything else then glasses thats made of titanium and except war ships :O

[antiswattt]

well whats the coolest metal powder you can burn thats easy to get

[antiswattt]

lol where can i get zirconium?

[antiswattt]

hm.. (= where do i get this neat stuff qX i wanna die haha i showed my friend and one of his friends charcoal powder when thrown on flame.. i burned my self 5 times haha

[sciencoking]

can you also dissolve it in ethanol? :D

[antiswattt]

hey.. you gotta try this!!! take zinc powder (fx.) or alumionium powder and then drop the powder onto a flame!! its so nice it lights really bright up and the zinc powder is the best iver tried yet.. i tihnk you can do with all metals just as long as the metal is powdered.. (: ive even tried with lead.. the zinc makes nice green flame and crackles and sparks..

[zsxwrsd]

ive heard printed on paper works to for a green flame

[3981784]

that paper in cattologs or in coupon books burns a greenish color

[megafeltch]

does copper oxide dissolve in ethanol

[Tingawinga5]

wow i wish a-level chemistry was like this if it was i wouldnt have had to drop it...lol

[diegolinbg]

how do you get copper oxide?

[Tingawinga5]

that green stuff that grows on copper

[oOMarioMafiaOo]

oh and tingawinga that stuff doesn't grow its copper reacting with the oxygen in the air creating copper oxide i like being literal

[glyceroltrinitrate]

One thing you also forgot to mention. Copper(II) Oxide isn't green, its black.

[spizzaza]

steal it from school? otherwise the internet, i bought a whole heap of bomb supplies... i mean harmless chemicals... of this guy on ebay.

[oOMarioMafiaOo]

LOL

[AlexDK5015]

If you just want a green flame, try burn copper sulphate:)

[3981784]

electrolisys

[10tsangvx1]

what are u spraying?

[sempertard]

Very nice. Also, boric acid works just as well, dissolves readily in methanol and is probably cheaper. I buy the gallon cans of SLX denatured alcohol (methanol) at home depot and mix two heaping tablespoons full of boric acid per 1/2 gallon. I put that mixture in a stainless steel bowl and light it. Table salt makes bright yellow, and lithium chloride makes a beautiful ruby red. Don't contaminate the mixture with any form of carbon as the yellow carbon flame will swamp out the other colors.

[seanofthesissons]

i did this in science today ironically enough haha

[xmrwaffles2]

same

[Jewcifer777]

We Blew Bubbles In Chemistry Today!!!

[descargaelbano]

@Jewcifer777 Michael Jackson blew Bubbles too. Bubbles was the name of his pet chimpanzee.

[54spiritedwill54]

wow dog thats cool :D

[NintendoDoc]

Luigi?

[extrasonic]

Stupid question, but I want to know if CuO can dissolve in ethanol ?

[zilali]

should do yea

[extrasonic]

Thanks. I'm going to receive my copper oxide soon, so I want to know.

[doco5622]

@zilali it dissolves in ethanol? i thought it was an insoluble base...

[TheMrWeedy]

@extrasonic

only hot cuo

[mcwario13]

@extrasonic no

[olaffub519]

would this be endothermic or exothermic?

[zilali]

Exothermic as by definition anything that burns releases heat.

[EdevoK]

@zilali there are come reaction in which things are burnt but heat is taken in and not given out that much ...

[98209276]

so when a hydrocarbon is added the copper oxide oxidizes the carbon? if so this could replace potassium nitrate [ KNO3]

does copper oxide have 2 oxygens or 3 i hope its 3 or 1 lol more deadly.

[zilali]

No the oxidation of the hydrocarbon is simply from it burning in the air. Even without the copper oxide it would still burn. The copper oxides function is just to provide a copper ion which gives it a green flame.

Copper(II) oxide has the formula CuO so it has one oxygen not two.

[EdevoK]

@zilali I think the compound is Copper Sulphate or Copper Chloride or Copper Carbonate ( the one u sued in the vid )

[AdultmentSystem]

ur face is a hydrocarbon

[pyromodder]

my face is a number of different compounds

[zilali]

Not really. It was in my kitchen where we have a stone floor and nothing else flammable was around

[EmotionZero]

How do you make copper oxide? I need to know!

[MOKO200]

sprinkle copper turnings on a burning splinter.. copper(II) oxide will be black in color.. :p

[SanitySource]

can u explain this in simpler terms please?

and does it give off toxic chemicals when burned?

[MEDICK93]

cool

[jako1250]

i found that brake fluid burns green!

thats not very healthy tho!

[ConcertPianist]

You can also use Heet (C) Antifreeze with 3 tablespoons of boric acid.

[MrHankkey93]

wow dog thats cool :D

[zilali]

I can't remember the exact amounts but it was around 4-5g of black copper (II) oxide dissolved in about 25ml of methanol which was put in a spray bottle.

[MDHmodder]

You can also use Boric Acid, or Copper Sulphate and Calcium Chloride (mixed together of course).

Both dissolved in alcohol or another flammable solvent will burn impressively.

Someday I wish to make candles that burn different colours.

[alimon4142]

...and poison the shit out of people? he he he

[MDHmodder]

And copper oxide doesn't?

Outdoor candles or torches of course.

Right now I am using home made black powder and mixing it with melted parrifin and got just what I needed... stars that last nearly 10 seconds

[derjew]

nice! Tii bad i dont live anywhere i can fire dat ten second stars into the air!
