boris_73 Posted October 9, 2004 Share Posted October 9, 2004 who knows how to make silver nitrate out of nitric acid and silver, i mean the exact method eg how much silver to add to how much nitric acid and how to get silver nitrate crystals out of the silver nitrate solution, Link to comment Share on other sites More sharing options...
Gilded Posted October 9, 2004 Share Posted October 9, 2004 Mmm... Silver nitrate. http://www.webelements.com/webelements/elements/text/Mg/key.html (See the vid with Mg, solid silver nitrate and water going *BOOM*) Link to comment Share on other sites More sharing options...
boris_73 Posted October 9, 2004 Author Share Posted October 9, 2004 wow that was with silver nitrate mg and water, at first i thought my computer was acting up because it was just a black screen Link to comment Share on other sites More sharing options...
boris_73 Posted October 9, 2004 Author Share Posted October 9, 2004 i know where to buy silver nitrate but its not exactly cheap for what you get its more cost effective to do it the way im trying to find out how it can be done Link to comment Share on other sites More sharing options...
budullewraagh Posted October 10, 2004 Share Posted October 10, 2004 are you trying to make silver acetylide or something?? don't; it's bloody insane Link to comment Share on other sites More sharing options...
boris_73 Posted October 10, 2004 Author Share Posted October 10, 2004 no i dont want to make silver acetylide, i have no need to make it.....yet no just a joke which is not very funny Link to comment Share on other sites More sharing options...
budullewraagh Posted October 10, 2004 Share Posted October 10, 2004 actually, a friend of mine was given permission to make silver acetylide for his last AP chem lab of last year. instead he chose to do something else:\ got a little scared Link to comment Share on other sites More sharing options...
boris_73 Posted October 10, 2004 Author Share Posted October 10, 2004 what you are aloud to make explosives at school,what kind of school do you go to we were never aloud to do anything like that Link to comment Share on other sites More sharing options...
budullewraagh Posted October 10, 2004 Share Posted October 10, 2004 actually, our school never does cool chem labs. in fact, the most "dangerous" materials we worked with last year in my honors chem class are 18M sulfuric acid and fuming hydrochloric acid. we burned magnesium as well. thats it though. the AP class (which i will be in next year) works with materials that are a little more dangerous. the last lab the AP class does is a student-designed lab where people work in groups of two and design their own experiments. naturally everybody wants to do explosives, and a friend of mine actually got permission to do silver acetylide.

boris_73 Posted October 20, 2004 Author Share Posted October 20, 2004 how many grams of crystals could you get from 0.1m of silver nitrate at 2.5ltr because they sell it at http://www.kno3.com for £65 but i can get 25g of silver nitrate crystals for £15 at http://www.silverprint.co.uk Link to comment Share on other sites More sharing options...
budullewraagh Posted October 20, 2004 Share Posted October 20, 2004 107+14+(3*16)=170 170/10=1.7 1.7*2.5=4.25 Link to comment Share on other sites More sharing options...
YT2095 Posted October 21, 2004 Share Posted October 21, 2004 I have several ounces of Silver Nitrate here as a saturated soln. collect as much scrap silver jewelery as you can (I scrounged old broken rings and necklaces etc...). dissolve that in Nitric acid, the soln will be Blue in color, that`s the Copper contamination, what you need to do is add more copper to displace all the silver, then filter it off when no more copper will dissolve (you may as well crystalise the copper nitrate for a later experiment) wash the silver powder thoughoughly in water and give a final wash with deionised water (you don`t want any Chlorine traces). then re-dissolve the now pure silver in the nitric acid, adding a little excess silver at the end and store in a dark glass bottle (I wrap alu foil around mine to make sure). the excess silver is to absorb any stray nitric that may become present over time. Thats how I made mine Link to comment Share on other sites More sharing options...
boris_73 Posted October 21, 2004 Author Share Posted October 21, 2004 thank you.how do you know which is the copper and which is the silver, and how much nitric acid should i dissolve the silver in at the begining and end i want a quite concentrated solution Link to comment Share on other sites More sharing options...
boris_73 Posted October 21, 2004 Author Share Posted October 21, 2004 you can also make photo prints out of silver nitrate i have the instructions some where Link to comment Share on other sites More sharing options...
YT2095 Posted October 21, 2004 Share Posted October 21, 2004 you`ll be in no doubt which is which the copper Nitrate will be the blue liquid, the blackish powder will be the silver, when I say add excess copper till no more dissolved, I mean a large peice like a water pipe off cut, so that you can pysicaly remove it after as for the conc, use conc nitric to start with Link to comment Share on other sites More sharing options...
boris_73 Posted October 21, 2004 Author Share Posted October 21, 2004 thank you very much, thats saved me quite a bit of money to spend on other things one more thing how much silver nitrate would i get back once nitrated, because i can get a 1 ounce silver bar of the internet at http://www.ebay.co.uk for £5. thats going to be one of the hardest parts distroying pure silver to make silver nitrate i just dont think i can do it Link to comment Share on other sites More sharing options...
YT2095 Posted October 21, 2004 Share Posted October 21, 2004 that`s why I used scrap jewelery given to me by generous friends you`ll have to do the math on that one, I gotta go out now, Cyaz l8r Link to comment Share on other sites More sharing options...
boris_73 Posted October 22, 2004 Author Share Posted October 22, 2004 what can you do with copper nitrate thats is one chemical i thought was quite useless Link to comment Share on other sites More sharing options...
YT2095 Posted October 22, 2004 Share Posted October 22, 2004 well why not try using it as a color additive to some Pyro stars? or just keep it as a neat way to store "Niric acid" for a displacement reaction with a more reactive metal when you need it C`mon dude, use your noodle Link to comment Share on other sites More sharing options...
jsatan Posted October 20, 2005 Share Posted October 20, 2005 I know this is an old thread. My question is when silver nitrate is hit by light it turns dark due to the impurities. If this is a liquid soln then how would you get it back to white from black(grey ish)? Edit, also when you add you copper to get the pure silver out does the silver just drop off? Because I thought it would plate the copper, not that silver plated copper isnt nice (roll up, roll up, get your best silver rings right here, lol ) I take it would make crystals which would be easy to remove?

YT2095 Posted October 20, 2005 Share Posted October 20, 2005 if your silver nitrate is White, there`s a problem already. I personaly keep mine as a liquid, with a chunk of pure silver in the blacked out bottle. yes it does plate the copper, but comes off easily in a conc soln, almost like a spongey mass. silver nitrate also doesn`t react to light all that much, Chlorine contamination making the Chloride of silver certainly will and often within seconds of a strong light when dry (takes alot longer when wet). here`s a fun one for you, make some of the silver nitrate conc, dissolve it 1:10 ratio and soak it up in white UNBLEACHED coffee filter paper, get 2 keys or anything that fits on the paper that you`ll recognise as a shape later, leave one half of the dried paper as it is with the object on it, and with the other peice, spray some salt water on it, let it dry in a dark room, place the object on it and put Both peices in the sunshine (a windowsill will do) then time how long it takes for the change to occur and note which changes 1`st. with washing afterwards, you can keep these papers too as your 1`st ever photograph homemade Link to comment Share on other sites More sharing options...
woelen Posted October 20, 2005 Share Posted October 20, 2005 Normally I don't like to give sources of chems, but giving a source for silver metal is not too hefty I think . You can get very pure silver (99.95+%) at http://www.emovendo.net at a price of $13 per 30 grams. Shipping worldwide is another $3 or so. If you combine orders from this company, then shipping almost can be neglected. This is a very nice source of very pure silver. Link to comment Share on other sites More sharing options...

This sunday just gone I went to the carboot, (big one here). And picked up a load of scrap silver (about 1oz at least). old lockets snapped chains etc etc. Only spent £3. Bargin But I'm waiting for an old Car bat (should of been this morning) to make some nitric acid, fun fun fun. Link to comment Share on other sites More sharing options...
YT2095 Posted October 24, 2005 Share Posted October 24, 2005 remember to do you best to charge the batt 1`st, the acid is much cleaner and stronger that way, and if you can, leave it to stand in a plastic pop bottle for a few days too, you`de be surprised just how much crap actualy settles Link to comment Share on other sites More sharing options...

I've been looking all over at the Car shops for a bottle of the stuff, but all I find is over prices water, lol. Dont you just love it, But until I place my order for other chems I'm happy to make do with this, if the gas is still the same. Link to comment Share on other sites More sharing options...
