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.

Man I love it you been putting out more videos

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! 💪

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!!!!

Thanks again for teaching us 😃

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 enjoy your videos,, very interesting,, Thanks

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

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.

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.

I like your energy man

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.

silversulphate into silverchlorite. that was great. ❤ thanks

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

Thanks Goran!

I always feel you leave something behind with precipitations

awe, i wish you did do the final conversion and melt in this video, yea we have seen it.. but something about that completeness and closure.. its nice. ;) haha

Definitely want to know the overall yield lol, you killed me not finishing it off to bar :?) Love your content :) You rock :)

I don't know what any of these terms mean, but I'm here for it.

Seems like a good idea to weigh the sterling silver into the solution and to weigh the recovered silver output. With the blue tint in the sterling sulphate solution would a cold filtration be beneficial to remove copper sulphate? Just to reduce the impurities carried over to the ingot.

Senior Chief, I hope you let us know how much silver was recovered in this process. Please keep the great videos coming!

Mr. SREETIPS, first off happy Father's Day. I have this 2-part series under my top. During my hands on education process, after I trained considerably melting and pouring, I moved to Silver extracting without Nitric first. As a newbie practitioner. it was painful and generated a lot of waste (one of my mistakes is that I accumulated 7-8 lbs of silverware from Thrifts and decided do everything at once). Anyway, I took my time and proceeded with high volume of liquids to re-process and avoid too much waste. I also found out a way to process AgCl directly without going through NaOH and Sugar. Boil AgCl in water. Let it (almost) dry, mix about equal weight of Na2CO3, some borax (references say 40% of Borax for 0.995 purity, I did not use that much), melt it in a ceramic dish. After cold, break off the flux crystal. This also worked for me when, after NaOH and Sugar, the salt was dark brown or black. Sorry if too basic, since I have not seen this process anywhere, just sharing my learning. Been suffering but learning from mistakes. Cheers!

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

Mystery is solved . Pls let know how much was total yeid all together on that stand

As long as it flares up when the salt goes in, it's got something left to react with.

Well done!

Hello Mr. Sreetips, I recomend to you the Textbook of Qualitative Chemical Analysis by Arthur I. Vogel. This textbook describes the reactivity of all metals and his compounds and i believe it will help you a lot to understand and identify whats going on on your reactions. At least helped me a lot when i was majoring chemistry.

Please do a video on extracting the sodium out of solution, now that would be cool.

Now the fun question: was it necessary to dissolve the silver precipitate prior to adding the sodium chloride, or could you have had a solution of hot saline ready to receive it for conversion to begin with?

That was awesome

You got some great viewers @sreetips!

Very interesting. 👍

Could you drop the silver from the silver sulphate solution with a piece of copper? Also, I think conversion of the solid chloride can be done if you let it touch a piece of zinc in slightly acidic water.

Hey Sreetips, you might want to put salt into your waste silver nitrate after dropping the silver using copper. If there is ANY silver left in the silver nitrate, the salt should drop it out as silver chloride.

Thanks so much for all the comments

You could try adding the sodium hydroxide directly to the silver sulfate solution, skipping the sodium chloride step. The silver oxide/hydroxide should come out just the same, leaving behind sodium sulfate.

Awsome video

Never hurts to double check

Super reactive with the salt while boiling.. Wow cool ✌️PT

When you try the paper coffee filters (paper because they do not tell you what polymers go into the other types), I would use them mostly for initial filtering... Depending on the quality of the filters, they could be used for more. I had worked in a few labs that successfully used certain coffee filters for recovery, but it was 20 years ago, and I would not trust any made outside the US/Canada... (Western Europe also, but I doubt you would find any from there).

Ty for showering that! That is absolutely need to no for me I’m sure

Thanks goran.

Hi sreetips! I just saw this, and realized you figured it out! Here are a couple cool things you could try for fun, and also for research. 1. It should be possible to create silver oxide directly from Ag2SO4 as: Ag2SO4 + 2 NaOH = Ag2O + Na2SO4 + H2O, but I couldn't find a reference for it, only formation of AgOH, which should work the same. 2. You could also take AgCl powder, spread thin on a tray, and expose it so the sun uncapped to produce pure silver as: 2AgCl(s) → 2Ag(s) + Cl2 Keep posting! :-)

I was just thinking that was why the yield was so low. Since silver sulfate is insolvable that’s why it crashed out when it was added to the water. As long as the solution was hot it could keep it dissolved but as soon as it cooled down the game was up. I wonder though if you could just do the lye and sugar treatment directly to the silver sulfate. 🤔 it might work anyway. 🤷‍♂️

Doesn't natural sea salt contain other minerals that would contaminate this reaction?

Sreetips were you in a band?! I was studying your videos and one of them was tagged with that information but I couldn't find music right away.

My takeaway was to heat the considerable amount of water to boiling prior to adding the cooled sulfuric acid and silver. Keeping the silver sulfate in solution and able to react with the sodium cloride.

Sreetips is awesome!!!! Navy man

could there be Germanium in mixture , it added to some silver alloys to reduce tarnishing

Anyone else thinking of Luke Skywalkers Aunt in the kitchen while watching? It's the sound of the fume hood with the beaker of blue liquid

Nice...! I was wondering what happened. Those candle stick holders should have been loaded...They were.! It was just hiding...!

wow, I have about 1.6 lbs of this that is all dried out, I am going to try this method. the 1.6 lbs has some copper and palladium in it but I have no way to melt the palladium.

Woah! No way! Dang.... Almost missed a bit more than half of your total yield... Yikes! Thank goodness for the fellow viewers! @Goran ..... Right on.... 🤘👍 @Sreetips .... I loved the comment about your doctor in the last one.... Jerry Atrics.... 😆 as for diet, do you only do raw, or do you cook the veggies sometimes? A friend turned me on to a baked recipe of Brussels sprouts that i can eat as a snack anytime of day... and I don't normally even like Brussels sprouts...

so a cost comparative please. is it cheaper to use this method or the same cost? it seems like it would be cheaper to me. will you continue using it or go back to nitric acid?

What is the pH of your solution post-salt?

I've got a ten-year-old datatainer of used photo fixer prepared from distilled water. There's definitely silver in the solution but there's a whole bunch of white and green precipitate as well. Any idea what that is? I read somewhere that sulfur can fall out of the solution.

I still think you can just add lye directly to the silver sulphate. That should make silver oxide and sodium sulphate, which will stay dissolved in the water.

I would be interested in seeing if the silver sulfate can be converted to silver metal with the lye/sugar method. If you have the time and material, please give it a shot!

just saw the previous video today was gonna say it was silver sulphate but was sure youd had figured it out

I love your videos! One question. Why don't you just melt the AgCl to obtain Ag, and leave out the lye & sugar steps. AgCl melts @ 455 C.

Ya that cold makes the silver pop out

So I am have been looking around and see that you can convert silver chloride by adding water to just the top of the silver chloride and add 1/10th the amount of sulfuric acid and stir with a iron rod. Have you ever done this? If this is the case seems a lot easier and less messy than the lye and sugar.

I am really enjoying your videos. I just find them so enthralling and I can’t explain why.

Do you recall the yield of the remaining silver from the silver sulphate?

Nice what was the final weight of Ag recovered?

so if i understand correctly by adding sodium chloride you have separated the silver and sulpher and in essence made 2 products silver chloride and sodium sulphate with some hydrogen gas released and possibly burned some sodium off as well?

Was I right or was I right. :-D

Have you tried converting the silver sulfate with sodium hydroxide to silver oxide yet? Very curious to see if that works.

So would you suspect that the gas coming off the silver sulfate solution when you add the salt is SO2? Any chemists out there?

Thanks, Goran and sreetip

Got to be honest awesome sreetips

It's a straight 'Double Displacement', 'Double Replacement' or 'Metathesis' reaction. (they all mean the same thing - the bits swap places) Ag2SO4 + 2 NaCl => 2 AgCl + Na2SO4 If you had thoroughly dried and weighed the Silver sulphate, ~69% of that weight would be actual Silver metal, plus you could calculate in advance how much NaCl to add. e.g. if it had been 50g of dry Silver sulphate, you'd need around 19g of table salt in there. The maths say the absolute Max yield of Ag metal would be around 34g Stoichiometry saves some of the guess-work, but certainly not all.

The comments on your videos are almost as fun as watching your videos. :)

Hi sir I'm from India and I'm a big fan of yours, can u help me out with one question? What is the weight percentage of silver in silver nitrate and silver sulphate ? Please help me out?

Would it b posible 2 do some other other metals pure tanttium wills b cool

Wait - what was the yield?

What’s the best way to recover silver from tollens reagent? It’s the waste from silver nitrate plating glass to make mirrors. I have a lot of waste.

I thought your yield was extremely low but I couldn’t tell you why.

+sreetips By the way, when say sugar is it glucose or sucrose?

I had a feeling it was silver sulfate.

Folks, today is the day I planned to run my first batch of Silver using the H₂SO₄ method. Thnx Mr. sreetips. As per advice from Mr. sreetips I will not bring the H₂SO₄ to boil. After I have Ag in solution, I will bring it to a moderate heat (warm it up basically) and add it to hot water, this way I am expecting that all - or most of - AgS gets dissolved without the need of the extra step. I have 3 beakers to have a moderately small weight of Ag being processed in each. For those interested, I am keeping a video log in my KZfaq. Let's Rock.

You got to film the rest we need to see the yeild!!

how many of you guys would've added the salt by the teaspoon?.... I know I would have....LMAO!!

Here early because of my disastrous sleep schedule 🙂

And was this a cheaper method using household ingredients?
