Hi Cody, here's my NASA gold and mercury story - My wife broke a thermometer on her gold wedding ring. Mercury completely coated the ring making it a shiny silver color. All the local jewelers I called were stymied, none had a clue how to remove it. I called the metal plating lab at my center (Goddard) and they said they would have a look. After much discussion and calculation, they reverse electroplated it, the mercury fell away, and the ring is fine. As a result, two NASA technical papers were published on the specific process citing my wife's ring as the test subject. Cool!

[@danhelwig]

Simply heating to solder temps vaporizes the mercury, use a powerful exhaust fan or a respirator.

[@birdseyeview1543]

Dan... First, this is from 6 years ago. Second, the ring is from the 1750's and experienced men with PHD's in metallurgy and it's history determined heating to be an unviable solution. Mercury was in direct contact with the solder holding the crown and stone in place. I trust that wisdom, here's why. Simply heating to solder temps as you suggest would have likely destroyed the ring, jewelers silver solder of the 18th century did not have the same composition nor melting point as in modern times. Details matter.

[@danhelwig]

Never considered the jewelry aspect, very little heat is required to remove mercury from placer gold old time tailings.@@birdseyeview1543

[@michaelperrone3867]

Hi Cody, Awesome stuff! Though solubility in mixtures of metals or mixtures of salts is not really analogous to solubility in aqueous solutions. For example at sufficiently high temperatures gold and mercury would behave like miscible fluids, and when lowering the temperature, the precipitate that forms would be an alloy of gold and mercury, not pure gold. Check out metal phase diagrams to see the steady-states for these dissolving processes in terms of temperature and composition. It seems likely that you have made a semisolid phase, and that the solid portion you removed was not gold but the solid portion of the semisolid melt, which is a specific phase of gold and mercury. The liquid portions were so similar in density and had so little gold because even with zinc in one mixture, the eutectic point for mercury plus basically any metal with a high melting point will be almost pure mercury. The solid phase that was removed probably has the higher density and 'solubility' you were looking for. Let me know if you have any metallurgical questions and keep up the good work.

Wait, I know that 1g of water is 1ml but how does displacing water make it have more mass?

[@alanpartridge2140]

I'll give two explanations they are equivalent but use different methods to describe it Exp 1 Because displace the water with the mercury creates a buoyancy force upwards on the mercury relative to the amount of water displaced, this reaction to this force (newton's 3rd law) pushes down onto the water and scale increasing the mass shown on the scale Exp 2 The displacement causes the water level to rise so the pressure at the bottom of the beaker increases (as Pressure=densityX9.81Xheight) as force= pressureXarea the force on the beaker and scales increases, showing an increase in mass on the scale Let me know if you don't understand what I said and I'll try explaining it again

[@benwilsonMMA]

Thanks! Yes that makes sence

[@srana8137]

[@jomiga1999]

Imagine the pain in the ass it would have been to try and recover the gold from the mercury toilet.

[@paulneilson6117]

I believe some ancient alchemy texts say that bismuth and gold will dissolve more because the gold and bismuth will form Au2Bi a compound. That will likely double the amount of gold you can dissolve. Then you can add that to antimony bronze and then after driving off the mercury a nice alloy will result.

What happens to a weighing balance in a vacuum??

[@MrxstGrssmnstMttckstPhlNelThot]

Akhil Sukhthankar That'd be cool, to measure the weight of the air pressure.

[@theCodyReeder]

Probably would need re-calibration.

[@Ergzay]

There would be no difference because air pressure presses on all the surfaces equally. To measure the "weight" of air pressure you'd need to pull a vacuum on the bottom surface of the scale.

[@nunomarques3701]

If two objetcs with diferent volumes where in the balance, you would be able to see a difference because the Buoyant force of air would disaper

[@trashhgoo]

I'm not sure about it, but there should be a spot under the surface where air pressure pushing up will not change (Where the surface contacts the sensor) and this should make a difference between both areas resulting in a "lift effect".

[@Rune.]

This video is as elite as it's own length.

[@Majromax]

From your experiments, I think you've made the assumption that dissolving gold in mercury will not change the volume of liquid, therefore you can find solubility by looking at a density change. Is this necessarily true -- does dissolving X mg of gold in (say) 10ml of mercury still result in just 10ml of solution?

[@dominicburns9989]

Your are right the volume will increase but only proportionally to the mass of gold dissolved in the mercury. The density is always just the ratio of the mass and volume and as the mass increases faster than the volume, the density is increasing.

[@Kiptanui]

So, a question I hope Cody will have time to answer: let’s say I had 10 kilos of gold and wanted to transport across the country (moving)...and wanted to put it in a form that anyone trying to steal something would overlook it. This sure looks like an answer. A big plastic tub of these “chalks” labeled lime pellets or something. Other ideas?

[@Stefan_W69]

Cody loves his mercury. Hope he doesn't regret it later in his life.

[@sheps5656]

Any updates on the digester?

[@frechjo]

A problem I see with the density as a measure for how much metal dissolved, is that is assumes the density of the amalgam is directly proportional to the ratios of metals. At least for other alloys, that's not the case. Some alloys have properties that are not in between the metals they're made of. Like bronze being harder than copper and tin, for instance, not something in between. The same should apply to density, as the atoms of a metal are progressively being introduced in the latices of the other metal. Nothing warrants the alloy density will progress linearly from one of the metals density value to the other's. Also note that not only mercury dissolves gold, also gold absorbs mercury, which alters its properties a lot. So you probably want to extract the mercury from that gold bar before you use it for something. Gold gets easily contaminated by both mercury and lead, making it a lot less malleable among other effects.

[@joshbrz8902]

Mercury does not dissolve gold that quickly the amalgamation process slows down alot towards the end of the process ive had a gram of gold dissolving in mercury for close to five months and its still amalgamating for you to do it in under 5 hours just seems incredibly absurd your video inspired me to do this and now i feel like ive been mis informed

Hey Cody I wonder what will happen with Coke and Mentos in a vacuum chamber I wonder if it would add gases to the vacuum or just have no reaction

[@danbodine7754]

It would add CO2 to the chamber and get it all messy.

[@arnavwadekar9642]

My guess is that it isn't possible in the conditions Cody has available. What I mean is that in order for that to work, the Coke and mentos set up would have to reach vacuum first. This takes a while. And while doing so, all the carbon dioxide in the coke could've boiled off. However, if he does manage it, it's gonna be great cause the air will expand more creating more fizz. Either that or it'll pop quicker and not much foam will come out.

[@ficolas2]

Arnav Wadekar Its imposible to do, and dumb.

[@YuzuLeanne]

Carson W I would like to see that as well.

[@Mostlyharmless1985]

My prediction is the coke would lose all its solvated CO2 and become a flat sugar water, which will react very weakly to the mentos.

[@norxcontacts]

How is he measuring the volume with a scale?

[@excinerus]

1kg of water = 1 Liter , the bottle cap is suspended from above with a wire, while plunged it supports the weight of the water directly above it, by pouring the mercury inside of it, you're displacing it's exact volume in water out of the cup, that water will weigh on the scale instead of the cup, you take the difference in grams and convert it to volume :D

[@norxcontacts]

So 1 gram on the scale is 1 ml of water?

[@garethdean6382]

At 4 degrees yes, not quite at room temperature. It works with other liquids too.

[@NicholasA231]

At 20c water is 0.998g/cm³, and data table I have shows mercury at 13.546g/cm³ at same temp, so, some maybe a third of the discrepancy could be chalked up to that, but maybe a more precise weighing rig is in order. After I saw your video about it, I used this method to get density of a supposedly nickel crucible. I was able to get precision of +/- 5/10,000, and results very closely matched published value for Ni. Thanks by the way, I tried before to use displacement like I remembered from school, (measuring overflow water) - not very precise...

Hello, i am from Germany, so please excuse my bad english. I love your videos. But one Tip from me: If you use a Syringe to filter the Mercury, you have to be very carefull when pressing the piston really hard(because you have a very viscous liquid, or many fine particles etc.). Because if you press too hard, the liquid can flow between the piston and wall of the syringe and fly towards your body. That happened to me before but not with hazardous liquids. The Syringe you used is, in my oppinion, better than the oney without a pice of rubber at the end of the piston but it still can happen.

Strange that the tin added in could explain some of the mass gold processing sites of the Incas in South America. Since tin mines are very near where the massed processing of gold occurred. Tin in ancient times only occurred a few small places on earth and it is very interesting that the ancients figured out that adding tin to the mixture would produce more dissolved gold than without. Hence Orichalcum may be a part of process.
