V64 reaction of copper and iodine - Kupfer und Iod

[imurdaddy1222]

that balloon was like my boner....

[kmncztms]

What is copper? I don't know the english names of elements :S

[mirceaabc]

copper is Cu

[talibanrules]

@kmncztms cu coper is used in wires

[th1nker21]

aun't this dangerous ??

[paronfisk]

Don't eat it...

[crazzedgunner]

booooo!!!

[MuchHarry]

very gay

Why not do the experiment in a sealed tube instead of putting a balloon?

[kaviaari]

The stopper would pop out whereas a balloon can expand when volume goes up. Any other mean of sealing would be unpractical.

[crmy]

if you used a bubbler then you wouldn't have to worry about a balloon popping. that is assuming the gases produced are water soluble or non-toxic

[Grundalizer]

@vmelkon Because it could explode due to pressure increase. The balloon allows for some leeway because it can stretch.

[slateflash]

The balloon looks sick.

[apauln]

you are on youtube, explain here...

[DXsamurai]

hehehe thats my....guess what I'm about to say hehehehe

[derkozten]

hehehe, finding the reason for this experiment is as simple as going to the link shown by Netexperimente. There, the experiment purpose becomes clear: mass conservation.

racist comment:

WA iodine so black like the bangala(bangladesh)!!!!

[joeylawn36111]

No the point is this: Iodine - normally a solid, when heated turns into a purple gas (sublimes). The iodine gas blows up the balloon. But when the test tube is moved to let the copper strip down to the bottom to be heated, the copper reacts with the iodine gas to form copper iodide, a solid. Since the iodine gas has reacted with the copper, the balloon goes back down.

You find the explanation (in english too) on the homepage, shown at the end of the video!

@joeylawn36111 so how did it lose .02 g weight?

[javikmt]

37.72 - after the experimente 37.70 where is the 00.02?? Thats the point.

[abeasu]

I think the point is that you can get an erection if you put a blow torch in you balls.

[javikmt]

hahahahahahha I think that too :p

[DXsamurai]

lol

The reason the balance reads differently is because this experiment is only a simple (crude) example of mass conservation. A latex balloon cannot retain 100%. The balloon is porous and allows some gas to escape, but it's an excellent way to visually demonstrate that the state of matter has changed.

If this were done with a series of vacuum tubes, you could approach 100% accuracy and precision, but still, imperfections will exist because no equipment is perfect.

what was the point off that one
