what are the bubbles made of? vaporized water?

[PlasticSmile32]

@bigbirdcrap Hydrogen gas. It is the bi-Product of the aluminum reacting with water to form Al3+  Which is what bonds with the CuCl To form Copper.

Provided, of course, that CuCl2 is the limiting reagent =)

[FreddieShowPan]

Hi, I was wondering how long it would take for this reaction to complete = no more blue colour?

Would the time needed for this reaction decrease if the molarity was reduced to lets say 1g Al /100ml of H20 (M=.37)?

[s1pacrat]

I think that the Al would run out first in this experiment.

The time depends on which reactant is limiting - if it was CuCl2 then lowering the molarity would make it run out faster.

[FreddieShowPan]

Wow thanks for the quick response!

Sorry if my question wasn't clear, but i was wondering how long this would taken given i could keep adding Al whenever it runs out.

Thanks.

I'm thinking of doing an experiment with this reaction regarding Percent Yield and i wanted to make sure that each trial doesn't take too long because i need a lot of data points.

[s1pacrat]

I think each trial would take maybe half an hour or less, if you were careful to not use too much CuCl2.

[FreddieShowPan]

Thank you SOO much for the help =))

Do you know where they got it?

[s1pacrat]

no, sorry.

[Ericmoney9596]

Where did you get the cupric chloride

[s1pacrat]

chemistry class ;]

[TeamTrogdor]

i love you. I have a lab report do on this reaction. you just cut my research time in half.

a very? what song(s) were used for this video bro?

[s1pacrat]

this is sash and avery...

first is Genesis by Justice, then Ready Steady Go by Paul Oakenfold, then Genesis again.
