    This is actually a fascinating experiment which demonstrates how gold nuggets and flakes can form in hydrothermal vents and quartz deposits, which are usually very acidic and full of sulfides and sulfates. The super-critical acid water dissolves the gold transiently, and it then nucleates around forming crystals quickly, building up on itself into lumps.

    iam doing experiment at rock suppsoedly contain gold by dissolving them at 30% h2so4 when greenish things sulfate appear(fe 2 i assume) i add h202 then yellow murky things appear i think i will achieve fe 3 state but no matter how many peroxide it was and full steering at hot temp, it always revert into clear greenish things again, i theorized somehow gold fe 2 ion prevent gold from being oxidized thus precipitated it what do you think?

    Gold will not dissolve in pure sulfuric acid. You need some sort of coordinating ligand (like chloride, bromide, iodide, cyanide, thiosulfate) in solution to keep gold in solution: otherwise the gold will reduce itself back to metal immediately.

    What you made here is known in chemistry as piranha solution. This is very dangerous to do as a casual experiment. The sulfuric acid is an extremely strong dehydrating agent. The H2O2 becomes a very strong oxidizer in the presence of H2SO4. This allows the mixture to provide a free oxygen that can disrupt C-C surface bonds, forming a carbonyl group. This activity causes significant disruption in the surrounding bonds. That’s why even though it didn’t harm the inorganic gold, it could easily destroy any organic matter. Also, if your H2O2 concentration is too high, the mixture can become explosive. Please be careful when mixing sulphuric acid with oxidizers unless you’re confident in your knowledge.

I don’t know if in solution with H2SO4, it decomposes to a safer mixture, or if the free oxygen release would sustain the reactivity of the solution. But, this solution when mixed tends to be exothermic enough to bring the reaction to 120C. Either way, you don’t want to heat H2SO4 to 140C. At that temperature, it would be able to dehydrate organics very easily.

    Hi, it is possible to dissolve it with H2SO4 + HNO3. But only if the temperature is high enough. The precipitation works then by adding water. This is being used to dissolve gold when its mixed with silver (carat gold). For carat gold you use the inquartation process as we all know. By using above described method you don't have to do this. Since aqua regia isn't working well with carat gold, this is an additional method besides the inquartation. One important thing. As soon as you add HCL to this method, the precipitation of the dissolved gold won't work anymore by adding water, which is logic as you create aqua regia by doing so..... H2So4 + H2o2 won't dissolve AU, but there is another thing which you can do by that. You can dissolve carbon. (epoxy, plastic...) => IC chips. This is better than just H2So4 alone.

    I know that some processes are counter intuitive. Such as inquarting: adding silver to remove all the silver from the karat gold. But the method you speak of, there is already water present in both acids. So adding water to precipitate the gold doesn’t make any sense to me. None of the professional refiners on the forum ever once made reference to such a method. Unless this is something new - or a hoax.

    Hydrogen peroxide with a few drops of the acid is what (theoretically) reacts with gold because the acid makes the peroxide a much stronger oxidiser. The other reason this was done the wrong way round is that you should never add water to concentrated sulphuric acid. You should add the acid to water (and your peroxide solution is mostly water) I'm glad you were very carefull.

    Caro's acid (also known as piranha solution) which is what you made isn't stable at high temps. I don't think it will dissolve gold regardless. It's great at dissolving anything organic though. Well it dissolves it, oxidizes it to carbon, and then oxidizes the carbon into CO2 at which point the solution goes clear again. It's sometimes used to clean gunk out of lab glassware. Needless to say, don't get it on you. It actually does what most people think acids do when it gets on your skin.

    You just started with the 2nd charge of h2o2 and I'm wondering if something important is missing that does what the chlorine does in the normal aqua regia reaction. Forgive me since I'm writing as you go. Dammit, Jim. I'm a physicist, not a chemist. 🤣 🖖‍ Don't feel bad, Sr. I failed in the experiment, too. We gained wisdom though. Later Edit: after reading a bit perhaps heating it was a bad idea? I have found h2so4 + h2o2 makes Caro's acid which is destroyed by heat? I also find Caro's acid is explosive. Well, now I find Caro's is not made with sulfuric acid. It is made with chlorosulfuric acid. There is that chlorine again. Hm… 🤯Caro's is h2so5 so where does the chlorine go and what would it do to the gold powder?

It would be fun to see if you could get gold to go into solution of sulfuric acid and a nitrate salt. Even try a lower dilution of sulfuric acid at around 30% with a salt to simulate using battery acid instead of drain cleaner.

    The hardware store sulfuric acid has an inhibitor in it that is carbon based, this is designed to prevent dissolving pipes. Adding the hydrogen peroxide creates piranha solution, which in turn attacks the inhibitor in the sulfuric acid. Essentially, you are turning the concentrated sulfuric acid to a high percentage of sulfuric acid, and with the added heat, you are boiling off the water byproduct while carbon dioxide is released. Add enough hydrogen peroxide, and you will eventually get piranha solution, not add enough and you will just increase the sulfuric acid concentration. For your carpet video, after turning it to ash, putting it in the piranha would get rid of the carbon based ash and leave your gold behind. Piranha solution isn’t supposed to dissolve gold. Edit, now that I’ve finished the video, I see you realized this and now I shall eat my hat.

    I think your idea is plausible. But, your procedure may be incorrect. When you add 30% h2o2 to acid, your essentialy adding water to acid. Which will create a lot of heat, decomposing the h2o2 before it can react. Additionally, for your stannous test, You might get better results by testing an h2so4/h2o2 mixture. A possible control test to determine if stannous chloride will detect gold in solution would be to react ag(cl3) with h2s to make gold sulfide. Add the sulfide to your mix, then test the solution with stannous. You might get a result by chilling your reagents, then premixing before adding gold or heat

    so this gives out the gold sulfate, the piranha solution, piranha should be boom boomy solution, you are able to directly electroplate gold from that solution, so aqua regia is not required, for refining gold, direct oxidation dissolving of gold with piranha acid, usually hydrogen peroxide oxidation happens only in acidic conditions, possibly other mild acids would also work with h2o2. did you measure the liquid you added. not conclusive evidence. microscopic amounts of etching (like with KOH) would count as dissolving.
