Turn Pennies Silver and Gold (Chemistry Trick)
In this video we turn copper pennies into silver and finally to gold.
Obviously it's a chemistry trick but still impressive.
First we get 30g of zinc sulfate and dissolve it into 100mL of water.
Zinc sulfate was made back in our video on making a copper sulfate and
zinc battery: • Make a Copper sulfate ...
If you don't have zinc sulfate or can't make it, you can also use zinc chloride. This can be made by simply mixing hydrochloric acid with zinc metal and waiting until the fizzing stops.
Then we drop in several cut strips of zinc metal.
Zinc metal was obtained from our video on getting useful materials from batteries: www.youtube.com/watch#%21v=knc...
The solution is heated to a boil and copper pennies, that have been thoroughly washed/cleaned, are dropped in. They must touch the zinc in order for this reaction to work. Leave it in for five to ten minutes.
The zinc metal dissolves and releases electrons that go into the copper and give it a negative charge. The zinc ions in solution now redeposit form a thin layer of zinc metal. Giving the coin a silvery color.
Now the smart physical chemist might wonder how this can possibly work. Overall we're going from zinc metal to zinc metal and at first it seems like we're missing something about thermodynamics. What is the driving force? I've searched the literature and there doesn't seem to be a consensus among scientists, some claim it's a surface free energy issue with zinc having a lower potential on copper than in free solution (at high concentration). Others state that its an alloy of zinc metal and copper on the surface. The silvery color you're seeing on the penny is actually a type of white brass, not pure zinc. This is thermodynamically more favorable than pure separate metals and thus serves as the driving force.
Anyway, whatever the specific chemical reason, we've now deposited zinc onto copper.
The most amazing trick is to turn it into gold. Simply wash the coin and place it on a hotplate heated to about 300 Celsius. As it heats the zinc will diffuse into the copper, forming brass on the surface that looks like gold.
Eventually it will wear off but the results are rather impressive.

I remember watching this video when I was 13yo and it was so fascinating to me. Nurdrage and Cody were my favorite science youtubers and I was getting into chemistry, I was very fascinated. Now I'm studying chemistry in university and 1 year away from graduation. I just came here to thank you Nurdrage and everyone else that got me into chemistry. Thank you from the bottom of my heart 😃

I scammed a dozen boxes of cookies off a girl scout once doing this. All those thin mints assuaged my guilt quite nicely.

Wow! I would love to do this. I've got somewhere around 500 pennies in a jar just sitting there, collecting dust. They would look so cool as gold coins. Simply amazing.
Very neat trick! It's like alchemy!
"Don't try and pawn this off as gold as the brass layer will wear off" Ha, my evil plan to get rich was instantly quashed.

Seems pretty cool for RPing.
I'm surprised you managed to make that panny look this good - I've done this experiment dozens of times turing a few chemistry expositions (we use a flame torch though) and we've found that unless coins were quite clean and free of tarnish, the resulting brass coat was inhomogeneous and lacked shine. As such we started using pre-cleaned or even newly-made pennies to make them look better. Your final penny looks pretty good though.

Almost a Magician's form of alchemy... awesome. i love science.
That's cool. Would be great for show or to just show to your friends.
hey in that copper sulfate battery video the zinc sulfate you made seemed to be in liquid form. is that going to be a problem because in this video it seems to be a white powder that you mix with water. Can I make the zinc sulfate in the way that you did in the other video and then just heat that up or do I need to find it in powder form?
How durable is the plating? If I had a bag full of these (for game coins) would they wear down quickly?
What do you do with the leftover zinc sulfate solution? It would be very helpful plz
That was soooooooooooo cool!!!!!!!
Is there a way to get it back from the silver of gold color too the original copper color?
Could you make a video about the cleanup of your reactions, especially this one (if you know how to dispose of zinc sulfate solution plz comment)
Yay! Your from Canada too!!!
that was cool!
I love your watch
REALLY CLEVER!!!
Thankyou sir to very easily you Aploded more videos
you sir are an alchemist
Hey, will these coatings wear off or are they permanent. ?
so did this just basically do a chemical plating? I just found your channel there is some really cool stuff on here. what the heck did i ever do before youtube?
Exactly what I was thinking.
If you use tin instead of zinc, what would be the proper electrolyte to make it bronze?
BEAST!
i like those videos!
have a question I have a large copper kettle that is lined inside with brass I suspect this is the process m kettle is lined years of use has worn the brass down would it be possible to use this process to refurbish the brass lining safely to continue to cook in it.
THIS IS SICK.. I DID THIS IN SCHOOL LAST YEAR!
looks cool :)
Whats that stove thing u used? I'm doing it for a science fair but I dunno if i can actually demonstrate it there.
Love it!
Hey I do not know if you check comments or would even know the answer to this but... I am looking to make a Penny resin table and would like to know if this would last if covered in the resin or if the layer will still wear off
Question; this is basically plating the copper in zinc right, then heating it to diffuse the zinc into the copper making brass. So my question is after the 10 minutes or so once the copper is plated with the zinc, would leaving it in longer create a thicker plating and a longer lasting brass finish? Or since the copper is coated with the zinc, is it as thick as it is going to get? I ask because I have some copper "Zombie Walker" coins for magic tricks and I would love them to have a golden finish.
I'm having trouble finding what temperatures hot plates can go to. Can you recommend an electric hot plate for this? (If electronic hot plates can indeed reach these temperatures?)
Unbelievable WOOOOOOOOOOOOOOW!!!
Hey, I think these are not permanent, so, if I care for these coins and their coatings, can they last for a time ?!??
Really cool, now i can make my own gold
Hey NurdRage, my chemistry teacher carries Zinc Nitrate Hexahydrate [ Zn(No3)2 . 6H2O ] Could I use this instead of Zinc Sulfate since both are soluble? (At least I think?) However then would I change the 30 grams in order to make a 2 Molar solution before a boil it? (I think the video looks like a roughly 2M, but does that matter either?) Thanks a lot!!!
Is zinc sulfate the only chemical usable or are there alternatives?
no worries, just open the video description, i usually include instructions there.
