Hey, I was waiting to see this. Definitely looks cool. I ended up converting the mercury sulfide back to mercury metal chemically (very messy). This definitely would have been a lot easier.

[@jerotoro2021]

[@tariqsamaien6215]

[@wolfsk1n]

Not really. Most of the mining videos are about building the mine and doing some fun stuff with it, only a few are actually about retrieving metal from it.

[@CatalystChronos]

Cody has a whole playlist of precious metal collecting / refining. I think they are referring to that and not so much his actual mine.

[@ScopeofScience]

Loving the gloves, Cody!!! This is the most relaxed I've been while watching your a chemistry video of yours :)

[@liquidminds]

Actually amazing that you can see the water evaporate in the time-laps. Unless you are too focused on the stunning images of the mercury dropping down of course. Great video, as always.

[@theCodyReeder]

Right?! you can even see the rate increase when the blue color starts absorbing more light.

[@Yotanido]

It's such a dramatic increase, too. I guess that makes sense, since it was almost transparent before, but it still surprised me.

[@JollyJoel]

Turn it on 2x speed and you can see it clearer

[@Sh4d0wch40s]

My mind was blown last week in analytical Chem. I am currently a bachelor's student and we are in the lab for instrumental analysis. The scales we have are so delicate and precise, down to tenths of milligrams, that when I put the beaker with my solution on to weigh it, you could see the evaporation of the water directly on the scale. With my 100ml beaker I lost 0.1 mg of water *per second*. Seeing it that directly kinda blew my mind after realizing that it was due to the evaporation of the water.

Cody, you are the person who has helped me decide which field of science I want to major in, I think I want to go into inorganic chemistry because of how amazing chemistry Is and how much you can do with it. Chemistry is basically alchemy but real.

[@TF2BackburnerNoob]

There's a mistake at 1:39. Cody says, "When you have a more reactive metal in solution, and a less reactive metal as a solid, those two metals will switch places". However, the opposite is true. A more reactive metal will replace a less reactive metal in solution, i.e when you have a less reactive metal in solution, and a more reactive metal as a solid, those two metals will switch places.

[@benfabriquediy]

Dear Cody, I'm a jewelery student and a spare time scrapper and wondered if there is an easy way to reverse plate the gold from computer pins to a piece of 24k gold? Something like reverse electro-plating maybe? If it's possible, I'd love to see that in a future gold recovery video of yours! Love the channel btw, great job!

i love how our chemistry teacher tells us to never put chemicals into drinking bottles or something similar and you put some of the most toxic stuff you have into a water bottle with "mercury waste" written somewhere on the side with half the original label still on it.

[@futboleroR10]

jort93z well that rule is just meant to deter retards.

[@trustthewater]

I would think it would be the other way around. Only an idiot (or small child) would strange fluid out of a bottle with "mercury waste" written on it. It would be a somewhat Darwinian deterrence (except for small children).

[@TheRedKnight101]

Glass is normally non-reactive well certain chemicals can eat through plastic. In a chemistry class safety is the most important thing, but if you know how every chemical you have will react with certain containers safety doesn't have to be top priority.

[@465maltbie]

Yes you should never reuse food containers for chemicals. That is true in labs and in industry. But at your own house then it is your decision. Now for me if I had kids around I would never use a food container for anything that is not food.

[@mozkitolife5437]

[@maxencealex4767]

I really like the way you explained (the seat in the plane), you should keep explaining alway like that. It might be strange for you to talk about these "basic" things but they are really hard to understand for people who did not study chemistry, but who are fascinated by it (probably like many of your users). Thanks Cody!

[@zhengqunkoo]

In the timelase, you can actually see white vapour leaving the glass. What was that black thing floating on the solution's surface?

[@theCodyReeder]

That was water briefly collecting on the glass as it evaporated out, You can also see that the rate of evaporation increased when the blue color formed and started absorbing more light. The "black thing" was some small drops of mercury held up by surface tension.

[@Martin.Jorgensen]

Cody'sLab so darker colour = better storage(/absorbtion) of heat?

[@stormbase3202]

MartinJ Yeah, things with a darker surface color will absorbe much more light than stuff with a brighter color (for example white)

[@MrSearker]

Yup. Thats also why dark cars get much warmer than white ones.

The fact that you can see the actual water vapour evaporating is pretty cool

[@sdkekl3el]

Hi Cody, its fun to see what you are going to come up with next! If you are open to suggestions, how about making mercury thermometers? Since you have shown how to extract mercury from rock, Hydro/Oxy torch using H and O2 from your electrolysis apparatus which could be used to form borosilicate tubes, Sprengel Vacuum pump to evacuate the tubes, and your fondness for mercury thermometers. It would be neat to combine several previous vids and make several for different temperature ranges and demonstrate calibration.

[@StreetMachine18]

It would be interesting to see what the difference is in thickness of the copper rod is above and below the water line with a micrometer. Is there a measurable loss of copper into solution?

[@louistournas120]

Perhaps you already know this: The mercury was in the form of Hg(2+) and copper will end up as Cu(2+). Therefore, fore each atoms of mercury, you lose a copper atom in solution. You can weight the mercury to find out how much copper was removed from the rods Mass of mercury * 63.546 / 200.59 = Mass of copper converted to Cu(2+) Or you can just weight the copper rods before and after.

[@whatevernamegoeshere3644]

Awesome video, it was cool to see the mercury puddle like that.

[@capt_fruit]

Why does the copper nitrate color the solution from top to bottom? Isn't it heavier than water?

[@jakubjendryka4554]

I think it is just heavier than mercury nitrate which hasn't reacted yet

[@thom1218]

If mercury nitrate spilled onto the plywood, it would soak into it and contaminate the wood. How would you decontaminate that? Why risk contaminating the wood at all if there's a plastic bucket under it?

[@alfoncejean8826]

thom1218 you could probably disolve the woods into some aqueous solution ( I'm not a chemist can someone confirm). Has for why using wood I have to gess it's more a convince thing. Working on an univen plastic top is very problematic, and if you don't protect the tray you could inevitably peirce it at some point.

[@silasmayes7954]

Call me stupid, but hydrogen is a metal?

[@randomfactsguy1386]

It has a metal form but usually its a gas

[@theCodyReeder]

yes, yes it is, sort of... at least under high pressure is behaves like a metal.

[@joldsaway3489]

Well, that's a bit of a gray area. It's normally a gas at regular temperatures and pressures, but it is theorized that it forms a metal at extremely high pressures and extremely low temperatures. It hasn't technically been confirmed whether or not this occurs, but that would technically make it an alkali metal

[@applegwava]

Joldsaway it technically has in the diamond cell.But that might have been a fluke.Or im not up to date in science news

[@seanwalton6208]

(The others sufficiently addressed hydrogen as a metal. I am take it in a different direction.) It is the only element that is effectively two disparate types at the same time. Naturally you see that hydrogen is on top of the alkali series, but some periodic tables places hydrogen in the halogen series, because it accepts (halogen) or donates (alkali) an electron. Hydrogen typically donates an electron, hence it behaves like a metal more often than a halogen. Halides (LiH) are examples of hydrogen acting like an acid. Hydrogen is listed in the replacement series both as a replacement option and as a marker. It marks the place where an acid cannot react with a metal without a redox reaction. (Nitric acid will dissolve copper, silver, and mercury, but a molecule of nitric acid has to sacrificed, and that is why nitrogen dioxide is generated.) Metals below the hydrogen marker are inert to non-oxidizing acids. Ignore the fact that hydrogen is a gas, for a second. In fact replace all the elements in the replacement series with alphabetic letters, so you won't be prejudiced one way or another. Li - A; K - B; Na - C; ...; H - L; Cu - M; ... Now look at the salts of each: "A"Cl or "C"Cl or "L"Cl They all look like salts--even the hydrogen. The fact that acids typically have a hydrogen bond does not mean that it any less or more corrosive. There is a caveat here... hydrogen has an electromotive value of 1.0, meaning that it will react with more energy than some other metals. For example, dissolving HCl in water will generate heat, because the water molecules are being aggressively ripped apart. On the other hand, CuCl2 dissolves with no more than a ho-hum -- even though it too rips apart water molecules to form metal ions. Let me continue addressing the replacement series concept. All the elements in the replacement series refer to metals. There is another replacement series that is more obscure. For example, all the halogen elements replace each other: pump chlorine gas in potassium iodide, a purple color appears, evidence of elemental iodine. I think I said... um... enough.

Selenium is highly toxic, but without extremely small quantities of it we will die. Oxygen and hydrogen are highly combustible but form water which all life needs to live. The toxicity and danger a compound has is due to it's chemical properties well the elements it consists of may be completely harmless in other forms.

[@xlkiritolx8156]

Cool. I had a messed up dream a few nights ago too. I was In some warehouse on the promenade, twas dirty and old, almost decaying in front of me, It was full of woodwork, and sandbags. There was a bucket mining cart that looked brand new, black with gold handles, I remember being really impressed with it... I dunno why, it was only a mining cart, i got in it and was acting like a kid in a shopping trolley, looked up and there was some old dude with a top hat, long greasy hair, a monicle and black clothing, he was stood under a lamp holding a lever. When he pulled the lever the main warehouse double doors flew open, a big breeze came in and the mining cart (and i) went wooshing out, down the street (like the bus on men in black 3?) shrinking and changing shape to dodge cars but crashing into everything else, but at the same time it was like going light speed through space, everything was happening sooo fast, then I suddenly stopped in a random street between 2 old vintage mint condition cars but the guy was there again, under a lamp post, holding a lever. He pulled the lever with a smile on his face a seconc time and I went wooshing faster than before but through nothingness, just darkness, like space without stars, I couldn't move, it was like I was g-locked in my mining cart, slowly everywhere started to change from black to red, the cart started to slow down and the sound of tracks came from nowhere, faded in like from a distance getting closer, The air was getting hot and dry and things started to appear, I could see the tracks, a "mountain" with clouds above it, Ash falling from the red flashing sky, then the cart stopped, There was a wall to my left side, I looked over the right side of the cart to see the ground around me, there was a thin path not enough room to get out though. I looked up, there was a sillouette of a guy on a horse stood at the top of the mountain, he was evil looking, Kinda lesbian (dyke) looking. I decided to get out of the mining cart and walk across the tracks the way I came, then some shiit happened i cant remember what, and i was in front of a stone door with a crazy picture on it. I could hear some jungly/carnival music, the door opened, a fairy appeared and spoke to me, a guy came out of the shade from behind the stone door and gave me a sheet of music paper with a melody written on it. On my way out, in my path was a big boulder but it looked more and more fleshy as i got closer, then suddenly it moved, out came arms and a head and a word, it said "Uh..............". Then i kinda knew it was dreaming. I was on gorgon fucking mountain from zelda. My brain was being a spastic, mixing up random crap... That's all I got. ✌

[@royjonesrampage6684]

[@KaityKat117]

Dihydrogen Monoxide (DHMO) is a colorless and odorless chemical compound, also referred to by some as Dihydrogen Oxide, Hydrogen Hydroxide, Hydronium Hydroxide, or simply Hydric acid. Its basis is the highly reactive hydroxyl radical, a species shown to mutate DNA, denature proteins, disrupt cell membranes, and chemically alter critical neurotransmitters. The atomic components of DHMO are found in a number of caustic, explosive and poisonous compounds such as Sulfuric Acid, Nitroglycerine and Ethyl Alcohol. Accidental inhalation, even in small quantities, can result in death. Prolonged exposure to DHMO in is solid state can cause tissue damage. Gaseous DHMO can cause severe burns. It's a major component in acid rain. Visit www.dhmo.org/facts.html for more information. Stay informed. Stay safe.

[@alfoncejean8826]

Killian Walker study have shown that 100 % of people that died had consumed dihydrogen monoxide shortly before their death. Personally I do not think this is a mear coinsidence.

[@KaityKat117]

Despite its dangers, DHMO remains largely unregulated by the EPA. It's used: >as an industrial solvent and coolant >in nuclear power plants >by the U.S. Navy in the propulsion systems of some older vessels >by elite athletes to improve performance >in the production of Styrofoam >in biological and chemical weapons manufacture >in the development of genetically engineering crops and animals >as a spray-on fire suppressant and retardant >as a major ingredient in many home-brewed bombs >as a byproduct of hydrocarbon combustion in furnaces and air conditioning compressor operation >in schools >as a cleaning solvent >sprayed on as a preservative in many produce markets

The blue color of the copper nitrate starts at the top, and seems to grow down. I would have expected it to seem to expand from the copper wires. A quick google search informs me that copper nitrate is in fact quite a bit less dense than mercury nitrate, explaining why the blue pools at the top and offering another reason that copper is a good material to use for this reaction: the copper nitrate flows to the top, leaving more mercury nitrate in its wake to continue reacting. Cool

@cody'slab I have a few questions I think you would find really interesting. I was talking with my dad about guns and we got wondering about a few things.. 1) would guns, or any projectile propelled via an explosion, work more efficiently in space due to the waste product of sound being eliminated, I know the vibration would still be present, but would that transfer back into the projectile? 2) and the most interesting question we thought, was why does recoil go up.. we thought of a lot of examples, including cannons, people holding guns to the side and every other gun ever!! Always go up when they are shot, even if your pointing the gun down the recoil doesn't go down, the recoil still kicks up! why is this??? I would love to get a reply! Even if it's a quick few lines!

[@grantw.whitwam9948]

Your time lapse is real impressive.

[@omniextrict830]

Been obsessed with mercury since child hood. loving these videos. hopefully you can do more to define the unusual properties of it.

[@icacisthebest7420]

I love your intros Cody. It's such a small thing, but it is so cool!

[@riniks112]

Cody badass living on the edge. Taming the mercury beast avoiding it's devastating bonds.

[@SHAD0WZOMBIE]

I especially like that if you watch very closely you can see the solution actually evaporate in the timelapse at the end

[@MEME-gr3op]

That was SUCH a beautiful intro! Would LOVE to have something like that in my home.

[@Tondadrd]

I like the explanations in this video. The process is simple so just a few explanations are needed but then everyone understand it well. (In contrast to some of your 'REfining precious metals' videos)

[@darknightx33x81]

in the future, you might want to use thinner copper rods to have more rods and increase the surface area, which means the reaction should progress faster. p.s. that Cody's lab sign was amazing.

[@stormbase3202]

Darknightx33x Or small copper tubes, so you have from the inside and outside surface.

[@alfoncejean8826]

Darknightx33x he did say that he chose this setup because its looks "cool" on camera....

The reacement reaction actually does work pretty well with aluminum foil as long as you use a very thin foil and control how much aluminum goes into the mercury nitrate solution. You want the reaction to immediately go over to aluminum nitrate and not predominately mercury/aluminum amalgam.

[@ledelste]

This is one of your best videos, Cody!

[@juleswernes]

reactivity is not the right term if I'm not mistaken. It's more about the reduction potential. Mercury is less driven to be in an ionic / oxidized state (has a higher electro negativity therefore more nobel than copper) than copper. It can be compared to the termite reaction where the more nobel iron in rust is reduced to elemental iron and the aluminum powder oxidized to aluminumoxide

[@whitebelt4ever154]

Professor Cody, thanks for the lecture.

[@Fudmottin]

That is pretty darn cool. Loved the mini-chemistry lesson. Very well presented. You should be a teacher.

[@ianchen5346]

Nile Red is the best chemistry youtuber there is

[@paulhollier6382]

Nicely done! Thank you, Cody. Your work is much appreciated and greatly enjoyed.

[@0xEmmy]

Here's an idea for time lapses: a lamp that only turns on to capture frames. if you want 2 weeks in 10 minutes (a 2016x speedup factor), 60 fps of playback will require 1 frame every 33.6 seconds. If the lamp is on 1s/frame, then it can be off 29/30 of the time. You may also want to consider long-exposure frames, to further reduce the lighting power needed.

[@denniswilhoite6715]

I had to watch that intro a couple of times- how awesome!

[@BadPete81]

Reaction looks really nice in timelapse.

[@bubblezovlove7213]

Hey Cody, I was just watching a video where a tuning fork was lowered into water and that was interesting but now I need to see some tining fork mercury experiments. I would imagine you could get some interesting patterns happening if you find some imaginative ways to resonate the body of mercury and not just it's surface. Maybe even expose individual balls of mercury to various frequencies and make them dance. All the best, from Ryan in England..... 😎🙏🙏🙏😎

[@HereWasDede]

One of my favorite time lapses ever

[@science_and_anonymous]

ah why did I not see it before!!! A displacement reaction. brilliant cody

[@guyhornibrook5661]

i do enjoy a good old cody video from time to time :)

[@sijmenkroon5972]

Wow ive discovered nile red 2 das ago trough your subscriptions and have been watching all of his videos awesome that you included him :D

[@TahCitrange]

I use your channel to fill my fantasy of wanting to be smart and do science type things.. I thank you

[@davinarivinos613]

That intro is amazing!

[@TradingLaboratory]

Sick Intro Cody! Looks amazing

[@tenki330]

very cool timelapse at the end, just awesome

[@Wakawakawaka281]

Love the intro some beautiful woodworking

[@Dinnye01]

It just feels nice somehow that my 2 favorite KZbinrs are friends. :3

[@jcamachoyahoo]

FullMetal that’s great !!!

[@jonasstrzyz2469]

Thank you for this. I always wanted to se liquid metal precipitate out of solution.

[@christopherleubner6633]

Mercury chloride or nitrate are used to activate aluminum to use it as s mild reducing agent for organic chemistry. Most well known for ammination of ketones. Ketone forms an imine with an amine, then the aluminum reacts with the water formed creating aluminum hydroxide and an amine from the original ketone. ❤
