Growing Copper Crystals on a Dime!
Ғылым және технология
Is it a penny? is it a dime? Is it an abomination? What hast chemistry created this time?
Using a solution of copper ions and a power supply, copper is electroplated onto the surface of a dime (made out of nickel).
This is a good example of a REDOX (reduction-oxidation) reaction, in which the copper ions gain electrons to be reduced to crystals of neutral copper metal.
The reaction is viewed under a dissecting microscope, with the time-lapse portions sped up by 100-200x.

Id watch a half hour of this, if you're wondering if anyone is interested in longer content. Love your stuff

The dime is just casually obsorbing the pennies life force
This is amazing - more like this please
Wanted to see it from a long time.. Thanks for this!!!
The copper on nickel penny grew like red algae But the copper lost from the copper penny I think it's the process of electroplating??😅

Great stuff! Could we get a timer on-screen somewhere so we can see how long the processes are taking? It's pretty easy to see that the footage is played faster later into the video, but I'm curious just how much faster. Just found you. I'll definitely be watching more videos.
I want an chem teacher like you

Were the sounds the actual chemistry happening, or someone eating chips in the background?

Surprisingly, a big bowl of Uncle Chipps sounds exactly the same a penny having its soul stolen by an electrolytic cell
infinite copper glitch
Great sir!
TY for burning some of the money supply and helping fight inflation.

Lol, just doing my part :)
Him: This reaction is amazing! Me: How he got so many Canadian coins? Amazing! Someone else: Silly American.
So sir is this a non spontaneous reaction coz an external voltage is needed to fasten the process of exchange of ions in the solution which otherwise I think won't happen as Cu is quite electropositive in comparison to Ni. So Ni won't loose electrons to Cu and bond with sulphates on it's own. I think we can predict a lot of such double displacement redox reactions on the basis of reactivity level or oxidation potentials of these metals.
I like a lot but I am sad because I don't have any instruments that we found in chemistry laboratory 😢😥

This one you can do with a 1.5 V or 3 V battery clipped to the two coins!

Mostly an older model Kyowa dissecting microscope. I have a cell phone adapter that let's me line up a cell phone camera with the eyepiece to record the video
My favourite subject is chemistry
You are working nice but this types experiment is available in my book
