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!
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.
There was a young lady named Bright Whose speed was much faster than light. She went off one day In a relative way, And returned on the previous night.
thank you cody. as an adult male that still enjoys learning about science but um well, got drunk instead of going to school and getting good grades to continue in a science oriented direction. i have learned quite a bit from you. which is totally ironic in the fact that i am sitting here having a few beers and learning. very awesome man
Cody'sLab some dental amalgams can leave a silver streak when they are hard enough. Cody you could find an old dental materials book that has recipes for mercury amalgams and the properties you can get from mixing mercury with other metals. It was really studied back when mercury fillings where used.
it's amazing to see you get on the trending list, I've been with you since 50k subscribers and first started watching you when I saw a recommend video in my feed and I said "huh looks interesting" that video was amazing and made me immediately subscribe
You know, because chemistry is often such a big part of your videos, it would be cool if you did a series getting a little deeper into the chemistry. Like describing why molecules have certain properties, which elements are likely to replace each other in them, etc. I know a bit about this stuff, but it's been a long time since I learned it all and I'd really like to know more.
Does anyone else realize he turned gold into a white powder seems very interesting to me how gold became a white powder like chalk has anyone heard of monoatomic gold spoken as about by David Hudson in his lectures
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.
I just want to know one thing: who are those 181 who do not like this video or any of your videos in the first place? What are they here for precisely, to see what? I love your videos. Keep 'em coming.
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.
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.
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".
Cody wakes up in the middle of the night to drink something. Stumble across a bottle filled with liquid, presumes it's water. Drinks it, tastes sweet he says. Goes back to sleep. Wakes up like a mad man going insane!!!!!
I've continually enjoyed your videos! Just keep yourself safe with any number of those fun solutions! I remember a time I accidentally got some developing agent onto my cloths, which was well known to cause cancer, but a SUPER big molecule, so less of a concern, so long as you don't ingest it. In any case, be safe and keep being cool!
I love your channel and experiments but most of all i'm absolutely impressed with your knowledge and the ease at which you operate while carrying out experiments.
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?
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.
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
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.
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?
Alan, another idea: Don't try to scam the brothers. You only end up to the river, and your last tought would be why didn't graduate instead to be fool opportunist!
Cody bro... would really like to offer an idea for ya, i haven't seen anything SPECIFIC on the matter, but i would truly love to give you the suggestion, you're the BEST!!! sugg: How to dissolve (remove) ALL organics from a circuit board using household or easily acquired chemicals (so nothing but metal is left and how to refine EACH metal out) would LOVE to see that on your channel bro!! Stay Awesome!!
Thanks Cody! This is the first you tube channel I m subscribing... brave guy you are! Previously I have worked on mercury... prepared Mercury sulfide (Black one)... during which I have gone through headache, Throat & eyes irritation and mouth sore... Even after precaution ???
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.
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.
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
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
Pretty much nothing, he recovered all the gold and mercury at the end, only the nitric acid and zinc were wasted. (The gold was expensive, but has been used several times and can easily be resold.)
Love your vids never subscribed because they were on my homepage, youtube should fix this honestly you'd have more subscribers when they stopped showing up however had to look you up noice vids keep up the work man
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...
He's dealt with micrograms before; if he were to take a standard blood donation volume, boil that down and extract he'd certainly have *something* if only a few grains of the metal.
ANGRY ALL-CAPS RETORT ACCUSING REPLYER OF BELONGING TO A HATED POLITICAL GROUP. FOLLOWING ACCUSATION THAT THEY ARE THE RESULT OF THEIR MOTHER HAVING INTERCOURSE WITH A GERBIL.
That density measurement technique totally blew my mind. I thought this should not be possible at all. This really got me wondering what other things I assume to be impossible which actually are quite easy to do... One thing though: Could you add an annotation to the video, linking to the video explaining the method? This should be more convenient for other people who do not know the technique yet :)
i think the reason for the number slightly bigger is the wire you used to hang the cap is quite large and its volume is considerable to the measurement. maybe thinner wire like fishing cord will yield more accurate result
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.
Cody, this is a video suggestion. Slime making has been sweeping youtube for a long time. It is so popular that often when people go into the store to get slime supplies, there is no elmers white glue. Elmer's is a PVA glue (Poly(vinyl acetate) (PVA, PVAc, poly(ethenyl ethanoate)). Somehow it interacts with borax and shaving cream to make slime. I haven't found anywhere where someone has done a video on the chemistry of it. There are a lot of variations like "butter slime". If you could use science to better the recipes it would be a HUGE video. If you search for slime on youtube right now there are about 9,290,000 results. It would be a popular video and a HUGE public service. What do you think? You could talk about whether there are any trace additives in elmer's that improve the results over a generic PVA glue. How the heck does it work? Somehow it is trapping fluid in molecules, obviously.
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!
Simply heating to solder temps vaporizes the mercury, use a powerful exhaust fan or a respirator.
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.
Never considered the jewelry aspect, very little heat is required to remove mercury from placer gold old time tailings.@@birdseyeview1543

What happens to a weighing balance in a vacuum??
Akhil Sukhthankar That'd be cool, to measure the weight of the air pressure.
Probably would need re-calibration.
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.
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

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

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

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.

@Cody'sLab Barometric pressure effects density. In Utah, your elevation will directly effect the your densities.
extact humor from the comment section
you can't extract something from a place that doesn't have it
This video is as elite as it's own length.
Such dissolve.
Much wow
I was entertained and learned something. Cody feels like Bill Nye for adults. Well done.

doctor what you must be fun at party's.
doctor what have you ever heard of something called a joke? Because that comment might be something called that. Search a dictionary for it.
doctor what your the kind of guy who thinks he is smart but is really unsociable and stupid
his right guys its 1st not 1nd idots learn to writee
Nice, I can expect another mercury video within the next few weeks!
I like pie

the pie is a lie
what flavor?

That density measurement technique totally blew my mind. I thought this should not be possible at all. This really got me wondering what other things I assume to be impossible which actually are quite easy to do... One thing though: Could you add an annotation to the video, linking to the video explaining the method? This should be more convenient for other people who do not know the technique yet :)
i think the reason for the number slightly bigger is the wire you used to hang the cap is quite large and its volume is considerable to the measurement. maybe thinner wire like fishing cord will yield more accurate result
Nice video, I always wondered how much gold would dissolve into mercury. And damn, almost a million subs!
Thank you for not pouring the mercury water down the drain, Cody.
Cody loves his mercury. Hope he doesn't regret it later in his life.
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.
Could you dissolve osmium on mercury to make it denser, or osmium doesn't make an alloy with mercury?
Something tells me Cody wants to be rich. Always looking for gold :D
God dude your like the king of random with a phd. Glad i found this channel
almost 1,ooo,ooo subs !!!!!! love you cody
you do all the dangerous stuff chemist always wonder and I love it and I love you
your knowledge is impressive!
That gold bar costs more than my monthly salary and this guy mixes it with mercury just for fun. What a guy.
Cody, this is a video suggestion. Slime making has been sweeping youtube for a long time. It is so popular that often when people go into the store to get slime supplies, there is no elmers white glue. Elmer's is a PVA glue (Poly(vinyl acetate) (PVA, PVAc, poly(ethenyl ethanoate)). Somehow it interacts with borax and shaving cream to make slime. I haven't found anywhere where someone has done a video on the chemistry of it. There are a lot of variations like "butter slime". If you could use science to better the recipes it would be a HUGE video. If you search for slime on youtube right now there are about 9,290,000 results. It would be a popular video and a HUGE public service. What do you think? You could talk about whether there are any trace additives in elmer's that improve the results over a generic PVA glue. How the heck does it work? Somehow it is trapping fluid in molecules, obviously.
Awesome video, Cody! I would love to see you clean up your mercury waste!
Always wondered how you would do that...
