@svendmusic The 10 ounces of silver would be 2.596 moles of silver. And assuming that silver is the limiting reagent. 2.596 moles of Silver Nitrate would be produced. So, theoretically 439.96 grams would be produced. So approx. 15.7 ounces. Although the actual yield will be lower than the theoretical yield due to experimental error and such.
If you want more information on how this was calculated feel free to ask. But unless you do want to know, I won't type out the calculations.
how much would a bar of silver like that cost? and silver is more conductive to electricity than stainless steel right? well how many times more? its an hho thing , im sure that i can have less wast power with silver
@17Blackreaper to control the reaction. If the bubbling goes way out of control and might overflow, or if it starts sputtering, you can simply yank the silver out by the aluminum wire "handle". The reaction stops, and you can turn down the temperature or dilute the solution at your leisure, then restart the reaction by lowering the silver bar in again.
So I can get 1000 grams of silver nitrate would like to know the proportion of silver that I use as many grams of pure silver use for 1000 grams of silver nitrate?, is to make mirrors, thank you
@Nurdrage This was a wonderful and enriching video! But I just have one question. Aluminium won't react with ethanoic acid but it does react with copper ethanoate. The same goes for nitric acid and copper nitrate. Will the Aluminium withstand the Silver Nitrate? I think a thin layer of silver is formed on the Aluminium. Is that correct?
@ScienceTry apparently i am not nurdrage, but i would like to answer this question.
alumimium withstand concentrated nitric acide because of it's formation of metal oxide layer
only layers can protect the aluminium from dissolving.
but when react with silver nitrate, it does not form a "layer", silver will only "attach" onto aluminium, the reaction procedure will not be influenced.
Okay so I messed up. I wanted to percipitate Silver from scrap dissolved in nitric acid but I got impatient and heated it up. I see this video and realize I'm stuck with Silver nitrate which is not what I wanted :( I now know had I left it alone it would have dissoved and I could add copper to get the silver back out in elemental form. My question is how do I convert the silver nitrate back to elemental silver? Please help me out NERDRAGE ! ! !
@jaws99099 if it's still in aqeous form, why don't you just add copper like you said..
but if you want pure silver, you can electrify the solution and silver will be reduced on the cathode, but i am not sure if the facility in your residence will allow this to be performed..

I did this with a 90% silver coin, and the stuff is contaminated to copper nitrate. How can I remove this? Is there a solvent that will dissolve CuNO3 but not silver nitrate?
@ScienceHideout Hi science hideout, yes there is a very simple way, just take the coin solution and add a copper pipe, the copper will dissolve and precipitate pure silver metal, filter and wash the silver metal then dissolve the silver powder in nitric acid to get pure silver nitrate. In fact I'm editing a video on this.
Hey nurdrage i think this can important for you and other..
:The relativ atom masses are to handel (addit) with (g/mol=x*10^-36) for the exactly molecularmass, divide it by the number of atoms and verb they paralell to the exactly ratio you want. You can to addit the sames atoms before do the paralell verbs.
It is a kind of magic sure.
Amazon.de sell an periodensystem with relative atommasses and more (study knowledge).
I like the texas instrument calculators (not the cheapest).
Sir is it possible to put it in the oven to dry(instead of leaving it out to dry), and is it cheaper to make your own silver nitrate instead of purchasing it. Also how much grams of silver and how much nitric acid will produce how much silver nitrate.

If you use a good brand of chemistry glassware such as Pyrex then you should have no problem heating it, and it will not break. You could easily google search the reaction to make silver nitrate, or look into any college level chem lab textbooks. I'm sure you can find the answers.
@Al3xX420 Stirling silver is about 7% copper. The copper dissolves quite well in nitric acid. Its presence is shown by the blue color of the solution. Our source sold us a silver coin and told me it was pure silver, but my daughter noticed was stamped "stirling" on the side. So we took it back and he gave us some silver that he said was for jewelers instead. We just finished dissolving it in HNO3 and there is a light blue color, so this has copper in it, too. (Post continued.)
@Al3xX420 So now we have a solution of mixed silver nitrate and copper nitrate, and we need to separate them. One way would be to place copper metal (eg electrical wire) in the solution. The copper metal exchanges places with the silver in the silver nitrate, leaving more copper nitrate in solution and silver metal crystals on the wire. They fall off if you shake it, so you get silver in the bottom. Continue until no more silver forms, and you should have all the silver at the bottom. (more)
@Al3xX420 Then filter and wash, and it should be possible to re-dissolve the (now pure) silver in nitric acid and get pure silver nitrate. I haven't tried this yet, one worry is that some copper metal may also fall off the wire so the stuff at the bottom will once again be a mixture of silver plus copper. It occurs to me that the copper would dissolve in cold nitric acid while the silver will not (much), so that might be a way of removing any copper impurities. Haven't tried this yet.
Hey, Nurdrage, your video says that NO (monoxide) is produced by the reaction, when then oxidized in air to NO2. But the reaction on your web site shows NO2 being produced directly. Which correct? Thanks, Anna (age 7) and her dad (too old).
@athaulfthegoth Dear Anna! Whether NO or NO2 is produced directly depends only on the concentration of the acid. If it is around 30%, NO will be produced. If it is 60% or above, NO2 is produced. But as NO is very likely to give of one it's unbound electrons, it reacts with the O2 in the air to make NO2, which is significantly more stable.
@2060017 Thanks for the info! It makes it a little hard to calculate how much HNO3 you will need for a given amount of Ag. Want to keep the HNO3 to a minimum. Any excess has to evaporate off if you want to get pure AgNO3. We've been silvering some mirrors (Anna and her dad), it's an elaborate process if you want to recover excess Ag etc, but so far good results. You have to heat the HNO3 if you want any reasonable reaction rate with Ag. I could write quite a lot about the experience.
@athaulfthegoth No problem! :) The way I learnt it was that nitric acid actually decomposes not only at 80C, but also when exposed to light! Silver mirrors are VERY awesome, especially when we want to determine if some compound is reducing!
I'd love to hear about your experience, though my goal is to make silver nitrate. What I thought about is to use NaOH to eliminate the acid and then evaporate the water but then there would be Ag2O, so I think that simply waiting is the best solution. Cheers!
@2060017 To silver a mirror with the Brashear process, all chemicals must be very pure. So I was concerned to get very pure AgN03. This can be done if you have pure Ag and pure HN03. The extra HN03, NO2 etc can be evaporated. We used a plastic container with a tin can of NaOH beside the evaporating dish to absorb the H2O and the acid gases. Container also keeps out dust. Takes a long time to evaporate. NaOH does not have to be pure.
@NurdRage Is Nitric acid the one i need to know between real silver, fake silver and sterling silver, and the same with gold? And, how can i know when i am holding real silver? What color does it become when it is touch by nitric acid? Does fake silver become green and the same to sterling silver, and real silver become yellow or what? And what about gold? Is the same reaction?
@reallyfunnystuff31 if you honestly thing dissolving metal in acid is like making crack then it's painfully obvious you know NOTHING of how to make crack.
Assuming that what I see there is a 1 troy oz silver bar and a 200 mL beaker, this appears to be a large excess of nitric acid. Can a smaller excess be used, or does the reaction not go to completion in those conditions?
What was your return in grams of silver nitrate, from your one ounce bar of silver. I only was able to get 47g of silver nitrate...What went wrong here?
I have done the reaction using 100ml of 70% nitric acid and one troy ounce of .999 silver like the one you showed, but I cut mine to smaller pieces. The silver was added gradually over a 45 min. time till it all dissolved. This yield seems to be very small, and discolored ( due to a little sunlight I'm assuming)..
Thanks a million.., this video is most helpful.. Just one Q. of concern...,
1st , there seems to be a excess of hno3 used in this reaction, and if so how is it removed from the final silver nitrate?
I see that you left it to evaporate and precipitate out of solution, but gave no warning of nitric acid left in the final precipitate , or if it just stays in the crystal structure of the nitrate when evaporated, leaving just h2o behind as a by-product.
I thank God Almighty for your love of chemistry, I don't mean to offend with the "G" word. Still, if one has no problem with ALUMINUM and HIGHLY CONSENTRATED NITRIC ACID, then why not use aluminum for your joints when distilling it. That is- aluminum should work when highly consentrated nitric acid DISTILLATION proceedures [WITH STOPPERS lined WITH ALUMINUM? I speak in liue of slow stickered vehicles, the box, part time only for many years. Again...THANKS A BILLION.
I dissolved a silver coin in 56% HNO3... but now the sollution is dark blue... Could this be some coppernitrate or what is this and how can I get rid of it...to purify my silver nitrate I thought about reacting it with NaOH so it will form Ag2O wich is not soluable in water filter it and re-reacting it with HNO3 to form AgNO3 and water...
Hey Nurdrage, how do you recommend getting crystals off of the glass walls? I have a bunch of copper sulfate crystals in jars, but can't get them off the side! Any tips?
@pyropakman however, I dripped a few drops of 98% sulphuric acid on to the silver bar and yes for the first half hour, there was nothing interesting happening. But slowly I could smell rotten eggs and tiny bubbles, possibly sulfur dioxide. It is also worth noting that my silver bar is not pure only 60%, the rest i presume it is copper.
But uh, Why are we destroying Silver instead of selling it? (aha! just a joke!)
Silver Nitrate is useful coz it can make Silver too!
If we put a pure Copper wire to the Silver Nitrate solution, then we can see the silver crystals produced on the copper wire and the solution becomes blue.
Displacement men!
I'm 14 yrs. In our country, schools teach us chemistry after 16 yrs.
Also, was planning to make nitroglycerin. I have 98% sulphuric acid and 68% nitric acid. I read on wiki that the solution of nitric and sulphuric 50:50 ratio have to be suspended in a ice bath before glycerin can be added or else it will auto ignite. Any other advice? also can i use crude glycerin from biodiesel production?
For nitroglycerin you need >98% HNO3. Mix your 68% with sulphuric acid, then carefully(!) distill it for pure HNO3. If I remember correctly the ratio H2SO4:HNO3 used in laboratory is 2:1, but might be wrong about that.
Make sure that it NEVER becomes so cold that it's solid (one touch = BOOM) - use a thermometer.
Also, make sure that all acid is washed out very well afterwards, otherweise it will be even more sensitive. Make no more than one drop to start.
Hey, I just bought some nitric acid with 68% concentration. As soon as I open the cap white fumes started coming out. But it is not the red fumes its white, is it dangerous? Also what do I do if I don't want the nitric acid?? what chemical should i react it with to make it harmless to the environment?
@aeroscope the fumes are nitric acid, so yes it is dangerous. but only if you inhale it. work with it in a fumehood or outside.
to render it safe, measure the amount of acid you have. Then measure out 1.4kg of baking soda for every liter of acid. Now mix the baking soda with an equal amount of *water* first. Then carefully pour the acid into the mixture of water and baking soda. it will fizz alot. when you're done, the solution can be dumped, it's just fertilizer now.
@rufflesisastibs77 I am 17 years old science enthusiast living in Hong Kong. In here, I can buy just able any chemical without permits except for cyanide compounds. With that said, I could buy hydrofluoric acid as well but have never bought it since it is so dangerous. So far no major accidents have happened so the government largely rely on the people's sound judgements to what they are doing or buying.
hey nurdrage I have a question.I made copper nitrate by using copper electrodes in an electrolysis in ammonium nitrate solution.can I make silver nitrate by electrolizing a ammonium nitrate solution?
How can you get your silver back? You have to dilute your crystals with distilled water and precipitate the solution with a sleeve of copper? Is that correct?
Hi I love your vids I was wondering if after I made the silver nitrate crystals they were placed into some water then I added sodium hydroxide If I could use it to electroplate with in a basic solution or would the silver percipate of what would happen thanks
Will this work if i use copper, zinc, tin, or even lead? I know it'll make a whole new nitrate, but will those metals work?

Question
If u have a silver ring that still have traces of gold on it
What will happen when u dissolve the ring
Will the gold settle on the bottom of the beaker ?

What was your return in grams of silver nitrate, from your one ounce bar of silver. I only was able to get 47g of silver nitrate...What went wrong here?
I have done the reaction using 100ml of 70% nitric acid and one troy ounce of .999 silver like the one you showed, but I cut mine to smaller pieces. The silver was added gradually over a 45 min. time till it all dissolved. This yield seems to be very small, and discolored ( due to a little sunlight I'm assuming)..
Any words of wisdom here?

Thanks a million.., this video is most helpful.. Just one Q. of concern...,
1st , there seems to be a excess of hno3 used in this reaction, and if so how is it removed from the final silver nitrate?
I see that you left it to evaporate and precipitate out of solution, but gave no warning of nitric acid left in the final precipitate , or if it just stays in the crystal structure of the nitrate when evaporated, leaving just h2o behind as a by-product.

@pyrojig The nitric acid, when in H2O is aqueous. When it is no longer aqueous, it is no longer acid.

@pyrojig Nitric acid evaporates when exposed to air, drying will deacidify your agno3.

I thank God Almighty for your love of chemistry, I don't mean to offend with the "G" word. Still, if one has no problem with ALUMINUM and HIGHLY CONSENTRATED NITRIC ACID, then why not use aluminum for your joints when distilling it. That is- aluminum should work when highly consentrated nitric acid DISTILLATION proceedures [WITH STOPPERS lined WITH ALUMINUM? I speak in liue of slow stickered vehicles, the box, part time only for many years. Again...THANKS A BILLION.

werwolf19861 1 year ago
I dissolved a silver coin in 56% HNO3... but now the sollution is dark blue... Could this be some coppernitrate or what is this and how can I get rid of it...to purify my silver nitrate I thought about reacting it with NaOH so it will form Ag2O wich is not soluable in water filter it and re-reacting it with HNO3 to form AgNO3 and water...

pyropakman 1 year ago
@pyropakman however, I dripped a few drops of 98% sulphuric acid on to the silver bar and yes for the first half hour, there was nothing interesting happening. But slowly I could smell rotten eggs and tiny bubbles, possibly sulfur dioxide. It is also worth noting that my silver bar is not pure only 60%, the rest i presume it is copper.
aeroscope 1 year ago
Really good man!
But uh, Why are we destroying Silver instead of selling it? (aha! just a joke!)
Silver Nitrate is useful coz it can make Silver too!
If we put a pure Copper wire to the Silver Nitrate solution, then we can see the silver crystals produced on the copper wire and the solution becomes blue.

Question - after the initial reaction is finished - you don't mention how to get rid of the excess Nitric Acid? Does it evaporate off with the water?

Is it essential to wait many days for the evaporation of the liquid to take the crystals? Couldn't I simply filter the solution to take them?

Also, was planning to make nitroglycerin. I have 98% sulphuric acid and 68% nitric acid. I read on wiki that the solution of nitric and sulphuric 50:50 ratio have to be suspended in a ice bath before glycerin can be added or else it will auto ignite. Any other advice? also can i use crude glycerin from biodiesel production?
aeroscope 1 year ago
@aeroscope
For nitroglycerin you need >98% HNO3. Mix your 68% with sulphuric acid, then carefully(!) distill it for pure HNO3. If I remember correctly the ratio H2SO4:HNO3 used in laboratory is 2:1, but might be wrong about that.
Make sure that it NEVER becomes so cold that it's solid (one touch = BOOM) - use a thermometer.
Also, make sure that all acid is washed out very well afterwards, otherweise it will be even more sensitive. Make no more than one drop to start.
LordBockzock 1 year ago
Hey, I just bought some nitric acid with 68% concentration. As soon as I open the cap white fumes started coming out. But it is not the red fumes its white, is it dangerous? Also what do I do if I don't want the nitric acid?? what chemical should i react it with to make it harmless to the environment?
aeroscope 1 year ago
@aeroscope the fumes are nitric acid, so yes it is dangerous. but only if you inhale it. work with it in a fumehood or outside.
to render it safe, measure the amount of acid you have. Then measure out 1.4kg of baking soda for every liter of acid. Now mix the baking soda with an equal amount of *water* first. Then carefully pour the acid into the mixture of water and baking soda. it will fizz alot. when you're done, the solution can be dumped, it's just fertilizer now.

@rufflesisastibs77 I am 17 years old science enthusiast living in Hong Kong. In here, I can buy just able any chemical without permits except for cyanide compounds. With that said, I could buy hydrofluoric acid as well but have never bought it since it is so dangerous. So far no major accidents have happened so the government largely rely on the people's sound judgements to what they are doing or buying.

@aeroscope Oh. Well i can see why cyanide compunds are restricted. Hydrflouric acid is some nasty stuff. I never want to even see it.
