They didn't put copper around the tops of buildings because it's pretty, although it is. When architectural copper gets rained on, copper atoms will wash down the wall...killing all the algae that tries to grow on the building. Shingles sold today have copper in them for the same reason.
Take note of very old paint on wooden surfaces that areboth neglected and exposed to the weather. You'll find that the majority that's still more or less intact is green... I expect due to copper-based pigments that inhibit microorganisms that would otherwise decay the surface and let the paint flake off.
Most lab technicians are like that. They are in the background doing all the work with lecturers in the foreground getting all the glory. I suspect he is also more knowledgeable in the practical and "real world" applications of science.
We'll look back at these videos someday and think 'wow the guy who created the unified theory of everything was just standing there in plain sight the whole time'.
Having watched several of these "Periodic Videos" I can say, with a strong level of consistency, chemists are a special breed. Like so many Latin students or members of marching band there is a distinct peak and valley for every individual on the electron spectrometer. Still this has to be one of the most underrated channels on YT. I love it !!
I just really like the color of copper in solution. I've also seen it turn darker blue when mixed with a base like sodium hydroxide, which precipitates copper hydroxide.
We used to fire the TOW anti tank missile on the range at Camp Grayling. Each missile has two hair thin copper wires that trail behind it all the way to its target up to 3600 meters away. The warhead of the missile has 2 copper cones with explosives around them.(shape charges). When the charges explode. The copper cones melt and are projected through the metal armor of the tank in the form of a copper rod.
"Hey Vinnie, and what if the coppers show up while we are, y'now, at work?" "Don't worry about it, Tony. Coppers have this blue blood, this hemocyanine thing, and they tire real quick, so you just keep running."
Amazing. I remember watching this video in high school and falling in love with chemistry. Now I'm in the fourth year of my chemistry degree and going to write a research paper all about copper this semester. fun!
@FUGGINGMAD I believe it is a magnetic stirring bar coated in some hard plastic. You can find much info about it on the web but in essence what happens is that you create a rotating magnetic field under the magnetic bar (inside the base of the device) and this makes the bar spin and then of course use this stirring motion to help dilute your solution.
I've been binge watching these videos this weekend, and enjoying them quite a bit. I've noticed is that everyone has a slightly different accent. Since I'm from the US I can't tell which region of the UK they're associated with, only that they are different. But they seem a bit more pronounced than US regional differences, although I could simply be used to US accents.
@McPrfctday it is magnetized iron or some other magnetic metal (it has to be effected by magnetic fields), and the plate the beaker is sitting on generates a rotating magnetic field that pushes it around without direct contact. It's an analog to induction heating. The same principle is used in electric motors.
Assuming you mean the reduction from Cu(II) in copper sulfate to Cu(I) in cuprous oxide, the solution it was reacted with was sodium potassium tartarate. An interesting thing about this reaction is that it forms a very well known reagent called the Fehling's solution where the aqueous solution of copper sulfate is Fehling's A and the sodium potassium tartarate is Fehling's B. The reagent is used commonly in organic chemistry to distinguish between aliphatic (not aromatic) aldehydes and ketones.
oh how I do LOVE these genuinely educational videos! And that professor is just... SO ... EXACTLY what you think of, when you imagine a university professor XD he fits it so well!
that is in fact,a very nice question!copper sulphate,in water disassociates into cu2+ and s04- ions.now,cu2+ ions is what gives it the blue color.normally,copper metal is red because it absorbs colors of higher frequency like green and blue and reflects the reddish colors.however,when it is ion(cu2+),it has less electrons.this changes its electronic configuration,and thus it now absorbs lower frequencies like red and reflects higher frequencies like blue.
4:32 the very last part of the Stone Age, prior to the introduction of bronze, is known as the “chalcolithic” period. That was when people started making use of copper metal deposits that they came across for tools etc. Of course, the softness of copper limited its use in this way. Then smelting of copper from ores was discovered, as well as how to mix it with tin to make bronze, which was a much harder metal. (Not as hard as iron--that came later.)
But as a matter of fact humans have developed sweat glands which allow them to cool down while chasing the rabbit while the rabbit would eventually tire out and would need to halt to cool down because they have a deficiency of sweat glands. So basically we would chase them for days but eventually we would reach them.
Not correct about going "deeper and deeper" for copper. There are huge low-grade deposits of copper ores (usually sulphides) waiting to be mined in open pits whenever the price of copper goes up slightly from extra demand. Once they begi production, the price drops again. The Bingham Canyon mine in Utah and operated by Kenecott Copper is the biggest open pit on the planet.
The crystal covered apartment that the professor talked about was done by Roger Hiorns and the work was titled SEIZURE. There is a small Wikipedia article about him, several low quality videos touring the apartment on TH-cam, and a descent video of the artist at the site explaining the process and the art itself on Vimeo titled "Artist on site: Roger Hiorns on Seizure" [7184407].
@sjcwoor Copper(II)- oxide is indeed orange, while copper(I)- oxide is black. The green color on statues comes from copper(II)- carbonate, which is formed when copper reacts with the carbon dioxide from the air.
This use of sodium potassium bitartarate is great. As an afterthought. Maybe a video on the Solvay process would be nice to do. I think it would help to actually see it in action. Then maybe a video on cream of tartar or the crystal in jams and wines could be done to show potassium bitartarate.
@McPrfctday The heating plate has a rotating bar under the surface and the stirring stick is a magnet, or the other way around. Thus when the bar turns, the magnet follows the turning bar and hence stirs!
@onlyreallifematters Plutonium is actually fairly harmless unless it enters the body. So, as long as you washed your hands afterwards, you should be just fine... Unless you were talking about the weight of the plutonium making you not want to toss it around.
My work takes me to alots of greenhouses. They have drinking water fountains. I noticed on one of them that read "Antimicrobial copper". What makes copper antimicrobial? Any special process?
5:19 There is a rather confusing statement about electrical and thermal conductivity. There are many reasons Iron (steel) is not used for wiring, it is not very ductile compared to copper and it is vastly more prone to corrosion. The property of thermal conductivity is not directly related to heat losses. Also I think most of the green buildup on copper and bronze architectural features is sulphates and chlorides. Carbonates form very slowly away from pollution.
Requesting one on Copper Sulfate, used widely during my chemistry classes at school, no idea what it does or what it's for or why it's used at the early stages of teaching chemistry.
Crustaceans use haemocyanin to transport oxygen because it can hold onto the oxygen more tightly than haemoglobin, preventing it from bubbling out at high pressures. Some divers experience an effect where the oxygen bubbles out of their blood (they use higher concentrations in the breathing mix) which can cause serious issues. I'm pretty sure haemocyanin has 4 times the affinity for oxygen, but this means it is transported and cycled much less slowly, thus wearing out the organism quicker.
Copper power cables are becoming a thing of the past for trains here. People simply cut it down and steal it, disrupting traffic badly. Also... what makes Vulcan blood green then if it isn't copper? ;P
@Serostern This is true, electrical wire is in the high 90s though. But still, there was some kind of legal thing about copper brake pipes, hence the alloy.
"so if you start running after a crab or lobster, it quickly gets tired, compared to running after a rabbit or something" lollll this guy always cracks me up
i did a little fishing round and only gold and copper are coloured metals as far as i could find. Can someone confirm? I find it odd that so many metals just appear silver/white/grey. I wonder if there are some coloured metals expected in the superheavy elements.
Kennecott’s Bingham Canyon Mine is the largest man-made excavation in the world, and is visible with the naked eye from space. 0.6 miles (0.97 km) deep, No we don't have to dig deeper. While mines in Chile have over taken the Bingham's production leadership that mine alone provides about 13-18% percent of the U.S.'s copper needs. One mine. worlds largest consumer up to 18% each year from a surface deposit. P.S. the amount of gold and silver pulled out of the mine is greater than the Comstock Lode, Klondike, and California gold rush mining regions combined. And it doesn't show signs of ending the vain till after 2030.... just sayn'
Wilson's Disease is actually a fairly common disorder as genetic disorders go. I have a few family members with it, and I have the fairly descriptive Kaiser-Flescher rings but very few other symptoms of the disease. Copper really is shockingly involved in biological life
There is alot of Copper in fast charge Lead acid batteries. When I change out cells in large batteries. The Lead melts away exposing a copper core in the battery post.
Copper can be recycled, and aluminium wiring can be used. There are cost/practical reasons why this is not currently done more. Suppose copper would really be running out: then the demand rises and the price goes up, the companies then have an opportunity to invest in R&D of new techniques. This is what happened with horizontal drilling of oil. As a free market advocate, my take is that you do not need to force those options thru government. Entrepreneurs will do it when it becomes profitable.
If you're referring to metallic elements, you've also got Cesium, the largest stable alkali metal which melts slightly above room temperature and reacts very violently with water and has a gold lustre. If you're referring to metal metals, you've got brass, bronze, gold alloys blah blah blah. But I think Cesium is the only other coloured metallic element, not counting black/dark grey.
This is a strange question but I once heard that copper could not turn into a gas, is this actually the case or is it that it just has a high boiling point? Again sorry for the strange question! ^_^
we need to recycle our rare earth metals much better than we do right now, especially with those which we need in the semiconductor industry are generally needed for Building electronics. Some of them like Cadmium are extremely rare from the start and are getting wasted in throw-away products like batterys. But i saw another video on the topic of recycling electronics to recover the precious metals which looked pretty much as we are indeed making progress; just needs to be kept in mind by everyone.
I'm guessing sulfuric acid. That's about the only thing that would turn copper oxide into copper sulfate. The rochelle salt just acts as a catalyst I hink, although it probably is dissolved by the sulfuric acid, to create sodium sulfate, potassium sulfate, oxygen gas, and water. I could easily be wrong though.
Two graphite pencil leads, copper sulfate, a nine volt battery, and two wires, you can make copper flakes to precipitate on one of the pencil leads. I think oxygen gas bubbles off the other electrode.
At a restaurant, one person asked for H2O. Another person sees him order water so he says, 'I'll have some H2O too.' (H2O2) After that, the second person had a terrible day.
Wilson's disease.. ah yes. the only actual medicine I ever learned from ''Scrubs'' :).. and I LOVE the colour change to cuprous oxide.. childish of me perhaps, but just beautiful. Really enjoying your videos, subscribed and slowly making my way through them. I mentioned the series to my son, who is home schooled.. and of course he already knew and was subscribed. Good lad!

They didn't put copper around the tops of buildings because it's pretty, although it is. When architectural copper gets rained on, copper atoms will wash down the wall...killing all the algae that tries to grow on the building. Shingles sold today have copper in them for the same reason.

Take note of very old paint on wooden surfaces that areboth neglected and exposed to the weather. You'll find that the majority that's still more or less intact is green...

Lead was also popular for roofs
3 years late but; why would you want copper to grow on a building and what kind of shingles are we talking about?
@Intellectual Ammunition ah TIL thanks! I actually thought people were talking about the shingles disease for some reason.

I'm gonna go chase down some lobsters on the beach and see how quickly they get tired now. :D
Thats unfair because humans evolved to chase down animals
Try chasing plants. Their chrorophyll has magnesium instead of iron or copper and they can't move at all.
Calvin Ball what does going to the beach have to do with this?
Lobsters don't live in the forest.
