The new periodic table of videos are awesome. I would like to see Chromium chemistry as they are very colorful. But, I did not buy any chromium compounds since they are carcinogenic, especially the hexavalent compounds. But, trivalent compounds are much safer and they are not considered as human carcinogens.
Except Barium sulfate, all barium compounds are toxic when ingested. On chronic exposure, barium compounds will cause lung disease as well. So, people should be careful when handling barium compounds although they are not as toxic as other heavy metals like Lead or mercury as professor said. If you drink the solution of barium compounds accidentally, you should consume dilute non toxic soluble sulfate solution such as magnesium sulfate,potassium sulfate etc to precipitate out the non toxic Baso4
just had an esophageal fluoroscopy, and got to drink some barium mixture. they made it taste like berries, and i thought that was a bit of a pun off of barium. they aren't kidding either the element is really heavy for the amount that was in the little Dixie cup they gave me at least.
They seem to always give you a lot of barium meal, much more than you would think was needed for a good picture, I think it is because you are going to throw half of it up anyway so that is why they give so much. The first bit is not too bad at all, but then as you take more it gets really nasty, at the last bit you are trying your best not to hurl.
Barium nitrate, chlorate, and carbonate are the most common chemicals used to make the color green in fireworks. I was surprised to hear that a salt of barium is ingested for increasing visibility in xrays, as the salts of barium used in fireworks are considered quite poisonous and never handled without a respirator. I would be interested to know what salt is used medically.
You may already be aware that lead is a superconductor, along with mercury and 28 other type 1 elements. Problem is that they need to be close to absolute zero, which means helium. The landmark was achieving a structure that made the transition at LN2 temperatures, as LN2 is vastly cheaper. It'd be fun, but I doubt regular crystals will show much of interest. It'd be better to spend money on understanding why the current ones do it to predict new structures
I believe Barium Sulphate is also used as a white paint in proffesional applications, for example measuring total output power of the lasers. That's my current university project, an Ulbricht's sphere. Anyways, great video!
They want the shavings in a neat little pile; the way she did it they all fall straight down into the foil. If she is moving the file around then it gets messy.
My favorite part of science is saying "Lets do this and see what happens" lol. If you have a lab coat on and say that you're smart, a flannel shirt and a beer and your retarded haha.
One major use of Barium is in the Drilling for Oil. It is used to float the drill pipes in the drill hole well it is being drilled ( Barium drilling mud )
Barium meals don't taste very nice, true. They also horrible to throw up again if you swallow a lot and can't hold it...
Barium IS toxic btw, but the salts used in barium meals are so insuluble that the body doesn't take up any of it. If you were to ingest a soluble barium salt, your best bet would be to first vomit right away if possible, and then chug a sulfate salt ASAP to get the remaning barium over in an insoluble form.
Worth mentioning that barium is actually toxic, however barium sulfate is highly insoluble meaning it isn't absorbed into the gut therefore passing through without poisoning people, soluble barium compounds can poison people relatively easily as it affects potassium ion channels in neurones etc.
Why did she have so many gloves on in the glove chamber (4 pairs I think she said)? Late on, she had the sample out in the open to pour into the water in the fume hood.
@captaintupelov The glove chamber is to protect the contents from the outside, not to protect the outside from the contents. In other words, it contains an inert atmosphere so the barium does not oxidize by contact with air and moisture.
My son had a barium meal, he was a champ. Most people end up vomiting at some point but my 7-year old managed somehow to keep it down, and when he passed it.. well, it was like a lead weight. Amazing stuff, and gross.
Yeah. Professor. It's me again. Barium is radiopaque, meaning it does not let X-ray penetrate.
Although it is true, that some scatter, or secondary, radiation is produced in during the process depending on several variables and random ionization.
@supergsx She needs glasses to see things clearly, she has goggles on because it's lab protocol and since barium is a very reactive metal, it is handled in a glove box.
When I was about 14 I had an X ray of my gastrointestinal system. I remember having to drink a lot of barium. It was hard to keep down it tasted so horrible. Then I had to sit for several hours to let it disperse through my system, then drink some more and wait a few more hours. They should really give that stuff some sort of fruit flavor for kids. :D
Professor. Correction. Barium does not scatter radiation but is rather attenuated, or absorbed, by the heavy element, much the same as lead.
Scatter radiation has a detrimental affect in diagnostic imaging to both fim and patient alike, and is kept to an absolute minimum at all times through a variety of techniques..
Scatter raises the overall radiation dose and has a greying effect on the images produced, thus decreasing sharpness and clarity.
@jackycck2222 To give the reaction extra energy, so you can see the emission spectrum (colour) of the barium when heated with a flame, basically it just makes it easier to see the flame colour :)
barium is quite toxic ( the proff said it wasnt) if a patient were to have the same amount of another barium salt they would die, the reason the barium sulfate isnt toxic is because it is insoluble and HCl in the stomach wont react with it
also what was that redish flash 6:18 it appeared to come from the calcium fluoride window
@gummel82 It's to prevent the Barium rod from tarnishing in the air from water vapor. As you can see from the final demonstration, it reacts fairly quickly with water.
lot of conspiracy nuts claim that the trails behind flying jets is actually chemicals being sprayed which has barium in it. the idea seems to have a pretty big following on the internet. a lot of them have the idea though that its to poison us, but barium isnt the best choice for that goal!
@lejink And, of course, only they can find evidence of this while not one person in the recognized media is willing to put their necks on the line to listen and expose this ongoing massive attack for what it is.
@talshiarr actually there was one story on it, which is where the conspiracy nuts got the barium idea from.
some guy tested rain water and showed the test results to the reporter, who then went on to read it in parts per million. the paper clearly does not say PPM though, the unit is in parts per billion. so the test shows levels well below allowable levels for drinking water.
still though people go on and on about barium spraying.
@asseeninYOURDREAMS There are non-toxic Barium compounds, but Barium itself is fairly hazardous - as you can see at the end of the video - because it reacts with water. Since people are mostly water, you wouldn't want to eat actual Barium, and you wouldn't want it touching your skin. Worse still, the byproduct of the reaction with water is Barium Hydroxide, which is caustic, so you wouldn't want that on your skin either. Gloves are necessary.
i have about 300 questions about this video heh, so what your saying is things like barium absorb much longer wavelengths so when we see an xray we see what is absorbed so we get an image of the barium sticking to our soft tissue? or say the calcium in our bones doing the same kind of thing? if things like this absorb these higher energy wavelengths they have to do something with the energy right?
@coldlogic1 Barium scatters the X-ray energy. Think about Superman, his x-ray vision can see through all but Lead, it is the same concept but humans use Barium because it is no toxic. The rays can't actually penetrate through the Barium so the bounce off.
@coldlogic1 yeah, it sounds like u have a fairly good grasp of it. with xrays, which have a pretty short wavelength, and a fairly high energy, the higher the atomic number of the element, the better it stops the xrays. It does this by absorbing them, or attenuating them. There are about 4 main ways this happens, but too long for a yt comment. the advantage of barium is its salt, (sulphate) is VERY unreactive(inert)so is safe for ingestion. Iodine compounds are used also,but are especially ...
@coldlogic1 ...useful for injecting into the bloodstream. barium, iodine compounds, and some others, when used diagnostically are called "contrast agents". Positive contrast agents. When air or gas is used, its a negative contrast agent. More frequently now, barium enemas are being superceded by at CT scan of a large bowel and rectum inflated with gas, and reconstructed in 3D. In the old days, air used to be used in the cavities of the brain! Imagine THAT! Thank god for progress, hey?
Nice Vid! Yay barium sulphate - it keeps me employed. I give BaSO4 meals, swallows, enemas, follow thru's, SB traces/enemas etc. I have heard so many of these comments lol. And yes I try it regularly. It also forms a concrete like blob in the bottom of the toilet afterwards. Barium sulphate is also sometimes used as a plaster in walls of xray/scan rooms, in place of lead, as a shield against secondary/scatter.
@jeebersjumpincryst I hear tell that the concrete-like blob occurs slightly before the bottom of the toilet bowl, which is one of the reasons why I'm glad I've never had to have a barium meal. Goes in like wet clay, comes out like crockery...
What a coincidence! I've just had a yucky barium meal today (in Japan a company is required to have its employees take a medical exam once a year) and there's this video. They gave me a purgative pill, but this damn thing is still in my stomach! Eeee!
They know what is going to be produced because they have worked it out beforehand or as is the case with all of the reactions shown in the video, someone else has worked it out before them and the experiment has been carried out many times. If it is dangerous, they don't do it, or they use a big stick to start the reaction, or they put it in a fume hood.
Isn't CaCl what we add to a cement admixture to create heat so that it can be used in colder environments? They also use it in canneries to keep vegetables from turning to mush when being cooked. But I was not aware that glass could be made from it. The only forms of CaCl I am familiar with are liquid or what looked like salt tablets.
I mean to recall that barium is actually very toxic, but can still be used for x-ray pictures because it's not absorbed into the metabolism by your digestive system.
It just occured to me, in all the vids in which you ignite items, I see you wearing only clear shielded glasses - consider the intense light and possible UV emissions. I weld and braze metals for my hot rodding hobby and if I (very rarely)forget to shield my eyes, even when only heating the metal, they feel dry and itch - the first warning signs of retina damage. Just an observation, please be careful. Thanks for the terrific vids!
i've had to GI scans with barium shakes. mine was fruit flavored, but still tasted pretty gross. it's very much like drinking ground chalk mixed in water. and you drink a lot.
I'd like to see a video on bismuth "melt in your hands" alloys. Also, in John W. Campbell's "The Atomic Story" he had a pic of a Periodic Table displayed as a sort of warped 3-D spiral with projections-- I'd love to know what advantage there was of displaying the PT like that and can't find the book-- think I sold it years back. Love to have a scan of the relevant pages, if nothing else... If displaying the PT like that as an advantage, I'll bet this would be the place to reveal it.
Great video. I had to drink a barium solution to test for tapeworms or obstructions and god, it was the worst thing I've ever tasted. Didn't help that I'm lactose intolerant and it tasted like milk mixed with chalk. It's a useful element, but totally disgusting to eat.
@Dyrwen You'll get no argument from me... worse than drinking plaster! A slight odor, but no taste, of peppermint. And the annoying thing was they couldn't even see what the problem was, even then. I had to be 'scoped to see my ulcers, which kick up as nausea instead of pain. Warning: if you have to drink barium, stay very near the bathroom for the next few hours. If you are lucky, you will have two minutes of warning...
2:50 No, no it is not. It tastes kinda like if someone had grape soda, but it was made with dull tasting grapes and then they added a iron-e taste to it and then add very dehydrated piss. Plus you have to drink 2 litters of it AND you cant just chug them and forget about them, you have to drink sip by sip over a hour length. It was one of the worst experiences of my life.
I need to send you a nice geode from Indiana with Barite in it. With it although it has a yellowish color you can still see it is and can be a transparent mineral.
I can certainly appreciate the difficulty of working with those gloves on... Had a HAZWOPER refresher today. Had to dress out in Level A gear and because the instructor was evil, we had to put nuts onto bolts, place golf tees on a peg board, and attempt to dial a phone.
The professor at around 3:00 compares barium and lead as possible x-ray blockers. As far as I am informed, barium sulfate is used for the purpose. And, I also know that barium nitrate is in fact really toxic, but this is due to its solubility. So, BaSO4 is used because it is non-soluble in H2O, therefore not interfering with the organism. Conclusion - barium itself is toxic, but any very insoluble salt (BaSO4 has a really low Ksp) isn't. Is it not so?
at 2:52 the prof says barium is nontoxic, but it actually is toxic,...the compound that people take for the x-ray is barium sulfate which like he said before isn't toxic
if you used a different heavy metal then yes that would be toxic too but the elemental barium is toxic
it could be that just the video was edited in an odd way where that doesn't sound clear
I've had a Barium meal (don't worry I didn't have anything serious, lol0. It's actually not that bad.. it's a bit pasty but it only lasts a couple seconds and the taste is endurable.
why does the female scientist use it in a fume hood? does it give a toxic vapour? or is it to prevent oxidation? because the surface that rod oxidized (apparently) pretty damn quickly from when the can was first opened, though no telling how much time passed due to editing
@badbobbyhughes It isn't exactly a fume hood. It is more like a "vacuum-chamber". It is a hood filled with nitrogen to prevent oxygen and water from getting in and ruining reactive elements like barium.

There are about 4 main ways this happens, but too long for a yt comment. the advantage of barium is its salt, (sulphate) is VERY unreactive(inert)so is safe for ingestion. Iodine compounds are used also,but are especially ...
jeebersjumpincryst 8 months ago
@coldlogic1 ...useful for injecting into the bloodstream. barium, iodine compounds, and some others, when used diagnostically are called "contrast agents". Positive contrast agents. When air or gas is used, its a negative contrast agent. More frequently now, barium enemas are being superceded by at CT scan of a large bowel and rectum inflated with gas, and reconstructed in 3D. In the old days, air used to be used in the cavities of the brain! Imagine THAT! Thank god for progress, hey?

Nice Vid! Yay barium sulphate - it keeps me employed. I give BaSO4 meals, swallows, enemas, follow thru's, SB traces/enemas etc. I have heard so many of these comments lol. And yes I try it regularly. It also forms a concrete like blob in the bottom of the toilet afterwards. Barium sulphate is also sometimes used as a plaster in walls of xray/scan rooms, in place of lead, as a shield against secondary/scatter.
Thanks Brady and Prof P :)

@jeebersjumpincryst I hear tell that the concrete-like blob occurs slightly before the bottom of the toilet bowl, which is one of the reasons why I'm glad I've never had to have a barium meal. Goes in like wet clay, comes out like crockery...

tubester4567 8 months ago
@tubester4567
They know what is going to be produced because they have worked it out beforehand or as is the case with all of the reactions shown in the video, someone else has worked it out before them and the experiment has been carried out many times. If it is dangerous, they don't do it, or they use a big stick to start the reaction, or they put it in a fume hood.

Isn't CaCl what we add to a cement admixture to create heat so that it can be used in colder environments? They also use it in canneries to keep vegetables from turning to mush when being cooked. But I was not aware that glass could be made from it. The only forms of CaCl I am familiar with are liquid or what looked like salt tablets.

I mean to recall that barium is actually very toxic, but can still be used for x-ray pictures because it's not absorbed into the metabolism by your digestive system.

It just occured to me, in all the vids in which you ignite items, I see you wearing only clear shielded glasses - consider the intense light and possible UV emissions. I weld and braze metals for my hot rodding hobby and if I (very rarely)forget to shield my eyes, even when only heating the metal, they feel dry and itch - the first warning signs of retina damage. Just an observation, please be careful. Thanks for the terrific vids!

I'd like to see a video on bismuth "melt in your hands" alloys. Also, in John W. Campbell's "The Atomic Story" he had a pic of a Periodic Table displayed as a sort of warped 3-D spiral with projections-- I'd love to know what advantage there was of displaying the PT like that and can't find the book-- think I sold it years back. Love to have a scan of the relevant pages, if nothing else... If displaying the PT like that as an advantage, I'll bet this would be the place to reveal it.

At least do a quick flame test on that rock. You should at least be able to tell if it contains barium.

Great video. I had to drink a barium solution to test for tapeworms or obstructions and god, it was the worst thing I've ever tasted. Didn't help that I'm lactose intolerant and it tasted like milk mixed with chalk. It's a useful element, but totally disgusting to eat.

@Dyrwen You'll get no argument from me... worse than drinking plaster! A slight odor, but no taste, of peppermint. And the annoying thing was they couldn't even see what the problem was, even then. I had to be 'scoped to see my ulcers, which kick up as nausea instead of pain. Warning: if you have to drink barium, stay very near the bathroom for the next few hours. If you are lucky, you will have two minutes of warning...

2:50 No, no it is not. It tastes kinda like if someone had grape soda, but it was made with dull tasting grapes and then they added a iron-e taste to it and then add very dehydrated piss. Plus you have to drink 2 litters of it AND you cant just chug them and forget about them, you have to drink sip by sip over a hour length. It was one of the worst experiences of my life.

The professor at around 3:00 compares barium and lead as possible x-ray blockers. As far as I am informed, barium sulfate is used for the purpose. And, I also know that barium nitrate is in fact really toxic, but this is due to its solubility. So, BaSO4 is used because it is non-soluble in H2O, therefore not interfering with the organism. Conclusion - barium itself is toxic, but any very insoluble salt (BaSO4 has a really low Ksp) isn't. Is it not so?

at 2:52 the prof says barium is nontoxic, but it actually is toxic,...the compound that people take for the x-ray is barium sulfate which like he said before isn't toxic
if you used a different heavy metal then yes that would be toxic too but the elemental barium is toxic
it could be that just the video was edited in an odd way where that doesn't sound clear
might want to clarify that

why does the female scientist use it in a fume hood? does it give a toxic vapour? or is it to prevent oxidation? because the surface that rod oxidized (apparently) pretty damn quickly from when the can was first opened, though no telling how much time passed due to editing
badbobbyhughes 8 months ago
@badbobbyhughes It isn't exactly a fume hood. It is more like a "vacuum-chamber". It is a hood filled with nitrogen to prevent oxygen and water from getting in and ruining reactive elements like barium.
