Copper - Iron Single Replacement (720p Time-Lapse)

This is a classic example of a single replacement chemical reaction, wherein copper ions precipitate out from solution onto the iron rod as iron atoms leave the rod and enter solution.

The blue color of the liquid is due to the copper ions in solution. You'll notice that as the reaction proceeds and the copper precipitates out, the solution loses it's blue color. The iron atoms in the rod give up their electrons to the copper ions in solution, so that the iron becomes oxidized while the copper becomes reduced.

Man, that looks pretty good full screen in 720p... what are the iron pieces?

@KulawyMan Thanks! It was just some thick iron wire we bent into a V shape. The curvature of the bottom of the test tube obscures the bottom of the "V", but it is a single piece of wire!

We're gonna do a lab on that in Mr.Chase's class. XD

:o Mr. Chase was just doing that in class the other day!

this looks really good, you do great camera work:)
