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?

@extrasonic no

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

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

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

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!

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

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

should do yea

would this be endothermic or exothermic?
olaffub519 3 years ago
Exothermic as by definition anything that burns releases heat.

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.

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.
