Converting That Precipitate to Silver Chloride WOW!

This is great for people like me that suffers from insomnia.

Super cool video! I love how exited you got. You truly do love doing this and it shows. Great work Goran for providing such an amazing learning experience for all of us.

Hi, Sreetips - adding a little bit of H2SO4 to the water would greatly enhance the solubility of Ag2SO4. About that "I'll turn off the heat, I think I've got all silver precipitated" - OK, but what, if you did not? Once the solution cools down, any Ag2SO4 left (if there would be any) will precipitate and mix with AgCl, and some would still stay in the liquid phase - hmm... I'd use, instead, a hot NaCl aq solution to precipitate AgCl - this way I could see when the reaction stops. That lil' bit of extra water won't make any difference, as AgCl is practically insoluble. Also, precipitating from hot solutions tend to produce bigger particles of the precipitate, thus easier to decant and wash. Using NaCl solution would make the reaction less violent as well, I think - as that bubbling you get every time you add salt crystals has more to do, I guess, with adding physical "boiling initiating centers" than it has to do with reaction itself. The situation we have here is a pure liquid in a smooth container being at its boiling point - but because of its purity and smooth glass walls of the beaker it doesn't have many "initiating/ starting" centers to actually start the boiling - and thus it tends to become sorta-kinda "superheated". The moment you add some "centers" (like, NaCl crystals or other solids, like sand grains) it starts to boil violently - and precisely to avoid such situations, small pieces of crushed ceramic material are added to distilling flasks prior to distillation - to assure smooth boiling of the liquid that is to be distilled. In other words, that "bubbling" is hardly any sure indicator of reaction still going on - my guess is it will produce this effect till cows come home, as long as the liquid is hot enough - at least this is my educated guess, so to speak . And it just occurred to me... That AgCl + NaOH reaction is basically a substitution reaction - in which a strongly basic metal "pushes away", from acidic "rest" a weaker base metal and joins that acidic rest itself. Same goes when one mixes CuSO4 or FeSO4 solution with NaOH solution - the result is Na2SO4 solution and insoluble base of either Cu or Fe (Cu(OH)2 of Fe(OH)2). Typically, such "bases" are pretty unstable, and sooner or latter they decompose into water and oxides of given metal - seems AgOH is VERY unstable and id decomposes into Ag2O almost instantly. What's the point? Well, I THINK that the whole process of converting Ag2SO4 into AgCl could be skipped altogether - looks like adding lye directly to Ag2SO4 would have exactly the same effect - i.e. precipitated Ag2O, that could be decanted, washed and reduced to metallic Ag with glucose or saccharose (a.k.a. "regular sugar"). Whad'ya think - good idea, eh? ;-)

Fascinating stuff. And good information to know. Thanks Sreetips and Goran! 💪

Man I love it you been putting out more videos

Thanks again for teaching us 😃

These two videos refining without nitric acid I found to be the most interesting because in my country nitric acid (salt peters acid) is considered to be a dangerous poison. It requires special permits to handle, own and buy. So thank you for showing this process.

That was awesome. I held my breath for a second 😅 when you added the first little bit of salt, i thought it was gonna boil over!!!!

I enjoy your videos,, very interesting,, Thanks

I hope I can be as good at recovery and refining of precious metals as You and others like Goran!! I'm just trying to learn as much as I can until I am ready to have a proper and safe set up! Just stockpiling as much as I can right now!! Have a GREAT Day!!!

I cant stop watching your videos.

You sure have rock steady hands my friend. It will be really interesting to see what your stock pot will produce. Who knows you may discover some new mystery metal eh, LOL. When you were introducing the salt you sounded like a kid in a toy store. It was kind of funny for sure. I am with you on learning something new every day. That lump on our shoulders would rot without that for sure.Great fun today for sure. I have never seen you happier my friend.

It's great to see how we all learn together! :D

I like your energy man

Thanks a lot for this video but I'd like to know if this process can be used to refine gold

IV learned so much from your videos!!!! Thanks sreetips...

Also I have done this de-plating silver off of silver plated items in Parana solution sulfuric acid and nitric acid. I did use salt water instead it seems to work pretty good.

G'day sreetips I'm glad you are back making videos again! Like or ways I love watching your videos some times people in the comments. Do help out a lot as you know now keep up the great work buddy I look forward to seeing the next video.

Thanks Goran!

FYI, determine the amount of theoretical silver you should obtain using the mass balance equations. It’s all chemistry! 😊
