Silver Production from Silver Nitrate using a Copper Pipe
Ғылым және технология
Here I show you how to recover silver from silver nitrate. I began by placing 130.5 grams of silver nitrate into 500 ml of distilled water. A copper pipe (cleaned first with a Dremel to remove the oxide coating) was suspended in the solution and left for 30 min. The silver nitrate reacts with copper to form crystals of silver metal and a blue solution of copper nitrate:
2 AgNO3 + Cu → Cu(NO3)2 + 2 Ag
The first and last 30 seconds are in real time, the rest has been sped up to highlight the reaction. The precipitate is then filtered, washed several times with boiling water to remove the copper nitrate, then melted in a high-temp oven to produce 82.87 grams of 98-99% pure silver.

wow this is actually very satisfying to watch i mean look at the crystals, das pretty noice and it keeps forming 10/10 would watch again (to relieve stress)
Just acquired two small jars of silver nitrate today, so had to watch how to convert it and this was the best video.👍
Very interesting video :). i have a question is it possible to use this method to refine silver from a film fixation liquid?
Amazing video
Beautiful experiment!.But what happen if we put separately copper in solution, and then,combine with the silver nitrate?
What does the ph need to be? I had a huge yield on my first try and somehow I’m getting worse using mostly the same material. Help!
is good to put urea, in stant copper is that the same please teel me.THANKS
Hi how can calculate the recovery and purity of silver?
help please ok I have one question I have nitric acid and a heated magnetic Stirrer & some silver that I have made all most to dust now I know when I put the silver in the acid it reacts and will deserve now I am to put a copper bar in to the silver nitrate to recover the silver what do I need to do about the copper reacting with the acid all so ? add more silver? neutralize the acid? or? thank you
how many percent you recovered from that amount of silver sir?
Very nice activeti
Good afternoon Sr g plz tell me that will we melt after extract? Plz reply plz Sr g
Can you do this with silver citrate?
how much did silver nitrate cost ???
So roi is 90% estimated right?
Dear Darryl. Thanks for your video. If I use a more concentrated solution of silver nitrate, like 500 gr in 500 ml of destilled water, may I produce the proportional quantity of silver as well? I've read that Silver nitrate has a very high water solubility (2190 gr/l at 20 C), so that means that I could make a more concentrated solution obtaining by that a higher concentrated copper nitrate solution as well. thanks.

Basically, yes.
Bit of sound andsome theory useful!

can you tell me where the 2 behind Cu(NO3) comes from? In the describtion there is Cu(NO3)2 + 2 Ag.. so? :D
@levichristman2958

The 2 comes from the elemental charge of the Copper (II). Cu has a +2 charge while the NO3 has a -1 charge.
Hi, I've been refining my silver using 50/50 nitric/distilled water mix. I need to ask you why your nitrate is clear and why mine is dark blue? The reaction is identical when dropping the silver from the solution, but I'm still left with a bright blue solution and I'm wondering if there's still silver left in there? I've kept the solution after filtering the silver crystals and added copper back to it just to see if any further crystals drop. The copper still mildly reacts but isn't producing more than a few small silver crystals over a day or so. Do you know how or if I can use the solution to try to remove any trapped silver by electrolysis? Just to throw another question at you, but I've also tried this with silver plate and ended up with a murky green solution after dissolving the silver plate in the nitric/water solution. Not sure why it went green, but thinking maybe the presence of nickel under the silverplate. When copper was dropped in to this solution, I got hardly any reaction.. I realise the silver content is low, but I'm wondering if the nickel could be interfering with the reaction? Any suggestions are gratefully received!

Paul Liff Seems like there might be other base metals involved. Is it possible you've mistaken silver plating for 900-925 silver? I did some silver plated spoons and the water turned blue/brown, and foamy. Electrolysis can always get the last bits out if you can manage the setup. Havn't done it yet myself.
Wait wait why is your solution crystal clear when most solutions are that pretty blue
After the copper precipitates all the silver. You filter and rinse. Can that be melted with a propane hand torch or does something else need to be done to it before melting?

@@drricket ok. Propane gets up to 2,000. But Mapp gas gets up to 3,200. So ok use Mapp to be sure. The main thing. Nothing else needs done before melting. See a guy said I can precipitate the silver with salt. But then I was told it doesn't work and it has to be put in the sun before it can be melted. But he didn't say how long, because he said salt doesn't work good. He said copper and melt. So I am checking, I don't want to mess up
I am doing this experiment to show Chem students what the reaction looks like and to figure out what is happening, but when I have done the experiment in the past, the silver that builds up looks almost black. How should I do the experiment different to make it that white/silver color that you got?

Hi, What is the point t of doing this? Hasn’t the solution already dissolved silver in the first place? Or is this copper producing more silver?

Note to the people trying this. Copper nitrate must be disposed of properly. Do NOT pour it down the drain. Nitrate is bad for the environment and human health.

Travis, I have no idea, I didn't do the calculations, but used the proportions listed instead. The molar mass of silver nitrate is 169.87 g/mol, so I used 130.5/169.87 moles of silver. divide that by .5L to get the molar concentration.

Actually the really rare penny is from 1943, when the US mint stopped production of copper pennies in place of steel ones because of redirecting the use of copper into bullets for WWII, so the 1943 pennies made of copper are insanely rare as they were only a few million or so made.
