50 Troy Ounce MEGA MONSTER BAR Pt2

[@atb002]

Sreetips, in the beginning the solution was evaporated too far - past the point of supersaturation. This is why from that point we see ribbons of metallic gold fighting to stay in solution, and the sparkles and flakes later on. In the end you’re not losing anything other than that gold that got caught in the filter paper.

[@ahmedlegins5497]

Mr. Sreetips my 16y.o. son gave the best compliment you can get from a modern teen. "Hey dad, that's actually really interesting..." & he honestly meant it!

[@bikinglikebecker]

it must be super saturated causing that effect.. When solvents are heated they have a higher carry capacity & when they cool down they precipitate.. 2:00 what an awesome visual of the gold... you can see the covalent bond pulling mass together coupled with super saturation & cooling

[@YzerWings]

Thank you for making monster bars lately. Us subscribers really appreciate it! I have the flu right now and KZbin is getting me thru it.

[@DatguyJ80]

I just wanted to add the theraputic qualities of your videos, so soothing

[@Dratchev241]

my theory of why gold was coming out after you evap it down to drive the nitric is, as you evap the nitric you also drive off some HC and only so much gold can be held by the solution per ml so as the nitric and HC gets evapped gold has no choice but to come out cause it has nothing to hold it. Kind of like how the air can only hold so much moisture and when it reaches saturation the moisture drops as rain/snow.

[@fightington]

Saturation is the term hehe

[@RyanEglitis]

Yeah, def want more HCl when evaporating down that far, preferably before it drops out of solution.

[@PaulBrown-uj5le]

That's what happens.

[@dcorp80]

It doesn’t work in that way

[@nathanvanlieshout7834]

I'm glad you mentioned it. I was thinking the exact same thing. It has happened before only when the concentration was far less.

[@ArielleViking]

Wow, those layers in the evaporated solution and the ribbons of gold crystals coming out of solution looked amazing. Fascinating video ❤

[@AndyGraceMedia]

Well that was just fascinating. Another example of the complex nanoparticle makeup of chloroauric acid solutions. As already mentioned you supersaturated the solution and it wanted to spit out nanoparticle gold as well as crystalline metal. That accounts for the intense colours which are a result of the Rayleigh scattering of light and a reason why modern medicine uses gold as a very sensitive indicator based on its weird optical properties. It appears you also forced it into gold(iii)chloride and possibly gold oxychloride + gold(iii)oxide when you added the peroxide. Those compounds don't like to hang together but the high concentration forces them to crash out of the solution. They're fairly unstable but they all have interesting optical properties due to the gold. Loved seeing microscopic gold rain in the beaker! Outstanding and without losing any gold either (except the tiny amount in the filter paper.). No contamination by the look of it at all.

[@JUST1N888]

Really enjoy watching your videos I’m a welder and a coin collector. Thank you for your service Sir

[@sreetips]

Thank you

[@CuttinEJ]

I think we’re seeing a very good demonstration of saturation. The HCl can only hold so much gold. It’s lighter than the much denser liquid below so it stratifies. As you add more HCl the upper layer gets larger and the bottom layer gets smaller. I’m only at 5:38 as I write this. My guess is that when it’s all done you’ll have about the same volume you had before you began your denox reduction.

[@StevenC.Shoner]

Redox!! You got things so concentrated that the H2AuCl4 underwent auto redox to 2HCl + Au(s) + Cl2(g) -- a source of the frantic bubbling even after it had cooled down. So Cool!! It's a tribute to your Chemical skill that the ceiling of your fume hood, seen in the previous video, is so clean...

[@disgruntledtoons]

I'm wondering if the precipitation seen @6:00 and onward can be developed into a way to precipitate the gold on a larger scale.

[@AdamAugustPhoto]

The problem is that it would likely precipitate some of the contamination from the original 995 bar as well. Perhaps filtering prior to evap would take care of some of it, but I doubt it would be as efficient. Plus you'd need to factor in the energy cost of heating the solution compared to SMB or gas generator.

[@sevenproxies]

Hello Mr. Sreetips! Love seeing your work and your method. The results are always spectacular! I have a tip for washing out beakers and such: use a spray bottle, it breaks the surface tension in pretty much the entire beaker and washes them good without awkward wrist movements!

Well done sir this was a very interesting drop I'm looking forward to seeing how this bar looks in the end thank you for sharing this six stars

[@copperinquarter]

I'd assume that some of the gold chloride crystalized as the solution evaporated and became over saturated, which then decomposed to metallic gold due to excessive heat. Evaporation should always be done at low heat and never boiling. This is your major mistake, Sreetips. Boiling should only be used for rinsing and never for dissolving or evaporating.

[@citronic23]

@@sreetipsooo yeh thats a great thought! Either way keep up the great content. I always enjoy watching and learning from your videos

[@mcwolfbeast]

Sreetips, It's pretty similar to what happened when you heated it to dryness: the chloroauric acid crashes out because of oversaturation. However, it doesn't like to be in its solid form and would likely be shedding chlorine or HCL gas to precipitate out the elemental gold. The science of supersaturation is a bit weird, though -- at least it's not possible to actually lose any of your gold this way :)

[@mattmallon6546]

Hey streetips got a question? What would happen if you just boiled the solution till it was a slug or dry powder. Could you heat it up and melt it into gold? What im trying to say is could you skip the stump out step? Thanks love your vidios

[@JJayzX]

The acid would just crystalize. en.wikipedia.org/wiki/Chloroauric_acid#/media/File:Chloroauric_acid.jpg

[@sreetips]

Evaporating to dryness, then trying to melt the crystals into metallic gold. I’ve never tried it, but my guess is that the gold would go up in purple smoke.

[@vinnycordeiro]

That solution got super saturated after the nitric acid boil-off, that's why the gold precipitated out of it, specially when you rehydrated it with cold hydrochloric acid.

[@chemistryofquestionablequa6252]

I’d expect it’s crystals of chloroauric acid.

[@vinnycordeiro]

@@chemistryofquestionablequa6252 If it were chloroauric acid crystals, they would dissolve after more HCl was added.

[@fightington]

​@@chemistryofquestionablequa6252yeah - i think thats what my man is saying

[@sreetips]

I suspect PGMs.

[@sreetips]

Correct, with a few particles of metallic gold. But not a bunch as seen here. Theres something else amiss.

[@DonariaRegia]

This is better than watching a magician, because this is all real. Physics on display in some rarely seen procedures. That gold precipitate early in the video looked like a swarm of mermaids in the ocean. There is a degree of art to refining, so many unexpected results over the years. This is top top tier content.

[@87bwadman]

Not only immicible, but your concentrated solution was super saturated. Gold was falling in and out on the convective currents. When you added cold HCl, it created a site of nucleation at the interface of hot and concentrated and cold and free of solute. Very very cool

[@gtgodbear6320]

9:38 What would happen if you let it reduce and evaporate to zero liquid at room temp? Would all the gold still be there or would some have evaporated?

[@sreetips]

It would still be there.

[@kurtremislettmyr7108]

I guess there's no way to avoid it. Everyone I've watched that makes it big on KZbin at some point goes from making videos of what they are doing to doing things for a video. When that happens they learn all kinds of tricks to maximize earnings, such as making shorter videos or bigger batches. And I guess it's the way of things, but it makes me sad every time and it feels like the end of something good. That said, I've really enjoyed your videos and your calm demeanor and methodical ways.

Good advice. I find myself worshipping wealth instead of Him. The world (the Devil) has a way of pulling you in and away from the spirit. And he uses GOLD to do it.

[@spiritofage8235]

When added HCl to the syrup, you've actually salted out the chloroauric acid from the saturated soln. Also, all the HNO3 should've been evap completely after soln reached >122° C (the boiling temp of azeotropic 68% HNO3 / 32% H2O is 121°) The same for HCl is 108°C at 20% conc azeotrope, beyond that temp no free HCl should be in soln. And no excess HCl means the chloroauric acid will decompose, especially at elevated temp. You should have some excess of HCl to shift the equilibrium. After gold is reduced, more oxidizer is needed to put it back to soln

[@chrisforbes3882]

Hello I’m new to this and was wondering ?? I don’t have to many components and I wanted the bacily put everything into nitric acid first to remove the maximum amount of silver before I try to remove the gold, will this effect the gold for example I know it won’t be a problem for Ic chips but if I have exposed gold like on boards would the nitric acid take the gold or am I safe just to do a nitric bath first on everything, the reason I ask as I have limited resources and can’t afford to do everything separately

[@larryevans7669]

Hey, Love this one sreetips! Maybe a word of caution. Your supersaturated solution is very hot, above the boiling point of water. I am no expert, but it might be possible to cause a steam explosion (yes maybe small) that could spew your extremely valuable solution around. But, it may be that the density of the Auric chloride keeps the water on top. Beautiful work BTW.

[@robertmarkosian6868]

Great videos by the way, I watch you all the time. This part about gold really interests me

[@87bwadman]

Hydrating with HCl while driving off the nitric, and keeping the volume no less than half your original HCl volume, should achieve the same result as reducing to syrup if you drive all the fumes off. With the benefit of no super saturated solution and gold crashing out.

[@MoreAboutStuff]

I wonder if that initial surface precipitate was gold coming out of a super saturated solution

[@dn2817]

You mention possible contamination. Was the ice distilled water or tap? Maybe one of your other ingredient? How “pure” is your acids or you stump out? Is it possible they had trace contaminates?

[@sreetips]

Tap water. I think there was some platinum group metals in that gold bar. That would explain the weird layering during the re-hydration and the layering during the precipitation.

[@ottolehikoinen6193]

Syrup, while a chemist might say, we have this Supersaturated gold salt solution, we add some hydrochloric to get it just fully saturated 10:15 I guess the boil of nitric was so efficienr it broke some of the salts into some other salt which is why you needed to rehydrate with H2O2.

[@b.c.9358]

Hot solutions can hold more than cold solutions, like when we were kids we made those rock candy sticks with sugar water that we supersaturated with sugar and when it cooled off the sugar would condense on the stick.

[@freddurstedgebono6029]

Feel like sulfamic acid would be better than evaporating down to a super concentrated solution to neutralize the nitric since once it cools that gold drops out of solution

[@williamfoote2888]

There's no contamination. That layer is set up from water, from the melting ice, being far less dense than your chloroauric acid. Your best bet was to using your magnetic stir bar to keep the solution, with ice, circulating while you add your SMB. It'd have allowed you to add your SMB at a small and steady rate with out the big -risky- fizz up.

[@someguy-k2h]

I don't know what the difference is between this solution and the one you made with the 24oz bar, but this seems much more brown. The other solution was an insane orange color that was almost glowing. Then you really evaporated this to a crazy concentration. It was cool to see, but kind of scary.

Chloroauric acid is not stable at high temperatures: with prolonged boiling it will decompose to gold, hydrochloric acid, and chlorine.

Once again, Sreetips is using too much heat here. You should always evaporate a solution on low heat and not boiling. The solution became over saturated, causing some gold chloride to crystallize and then decompose to metallic gold due to the excessive heat.
