Copper (ii) chloride Aluminium reaction

[magert123]

what does it mean when green crystals appear at the end of reaction?

copper*

@jzlACoSTE Thanks for that I'm surprised no one else noticed yet

[jzlACoSTE]

@Ralphgtx280 haha you're welcome (:

Here are at least two or even may be three reactions:

1-st is 3CuCl2 + 2Al = 2AlCl3 + 3Cu(precipitate)

2-nd is AlCl3 + H2O = AlCl3 * 6H2O (hexahydrate) + t(a lot of heat - water starts to boil)

and if 3-rd reaction takes place, then it is definitely 2Al + 3H2O = Al2O3 + 3H2

@fesss83 Yep Ive got the equations in the description. I don't feel the hydration of the aluminium is nessisary to include as the equation I gave stated that reactants and product (where appropriate) where in an aqueous state

also the reaction of aluminium with water is definitely occurring, off camera I ignited some of the gasses coming off and they burned well, If you would Like I can take a stoichiometric mix of Al and CuCl2 and put them in water and a green colour will be seen

@Ralphgtx280 If the unprotected aluminum is reacting with the water, then why doesn't aluminum foil react water vapor in the air?

[Ralphgtx280]

@plrokster309 Thanks for your question, Aluminium selfe pasivates (forms a protective oxide layer) this protects the Aluminium from further reaction an experiment you can do at home is to take a piece of aluminium (must be thicker than foil) and sand it with some fine sand paper you will see nice bright metallic aluminium beneath mark the shiny area with a permanent texta than leave it and eventually you will notice the color returns to the original

what is the chemical eqution of this reaction

[Ralphgtx280]

@cristiquehan I added to reactions to the info bar sorry for leaving them out

[poprocz]

I don't know much about the chemical reaction there but I do know a darn good camera when I see one.

Quite nice video.

[Ralphgtx280]

@poprocz thanks its the Panasonic lumix TS1 its water proof and shock proof (there are some underwater videos and some dark use of the camera on my account also)

[Ralphgtx280]

yeah you sure do I did that previously but didnt video it (it doesn't show up briliantly on camera)

[panzuman]

if you light that hydrogen you get the most beautiful blue flame because of the coppor preasent in the steam

[Khalastas]

I like it, very nice.

You had a good camera!

[Ralphgtx280]

@Khalastas Thank you its the panasonic lumix TS1 it does full HD and works underwater
