worlds wettest salt
Edit: lol i recieved a notifcation of a comment i made 3 years ago to find it has a lot of likes and realise how wrong my comment was, but then i recalled it was written when "Is water wet?" was a fresh meme, that's why this comment was considered satire
To be fair, that would probably be a substance that is at least 51% salt, and at most 49% water, or other liquid.
+I'm Too Lazy For A Proper Name Ever heard of a new word called "joke"
Minhao Lee World wettest salt would be quite the opposite of that. Here you can see water with highest % of salt in it, and you need with lowest salt percentage, so there is a lot of place for water.
Its actually the world's driest salt that is still in solution.
Worlds saltiest wet
"Unless its taste is logarithmic". Priceless.
cicci0salsicci0 The exact same thing came to my mind when he said "it will taste twice as awful"
cicci0salsicci0 If taste works like the other senses, it must be logarithmic, but the perception is, not the amount of stimulus required. If I'm right, then water with twice the salt would not taste twice as salty, but much less than that, just as you need to grow the loudness of a sound or the intensity of light exponentially to give the impression of a linear growth. But I don't know!
Taste almost has to be logarithmic given the many orders of magnitude over which we can detect many tastes. According to the Weber-Fechner law, all physical sensations are logarithmic (in the sense that the just-noticeable-difference of a stimulus is directly proportional to the size of the stimulus).
Turn it up, I can't taste it!!!
@Sunamer Z
So my foreskin detects pleasure logarithmically?
still not as salty as the average csgo player

Less salty than the losing Splatfest team.

all the tears of my h8ers end up there :P
"The water in Ethiopia is hotter than the water in Antarctica."
No kidding XD
Lol
As a scientist, its your job to give every single detail even if that detail is so logical.
@@lifeofsoutypjsweat4653 lol
Life of Souty,PJ,SWEAT or differently said: if the fact, that water on the equator is hotter than water in Antarctica is trivial for you, I am sure it is also trivial for you, that warmer water has a higher saturation with the mentioned salts (which I think many don't know). If not, this statement was relevant to the explanation.
@@TomJacobW I will remember this. Thank you
went to the comments to see saltiness comments, was satisfied.
Alexithymiack you mean saLtisfied?
did you mean saturated?
@@sheikchilli8670 salturated.
i'm still salty that prof martyn didn't talk about what the maximum concentration of salt can be in water at rtp.

This is where they are baptized.
You mean Iodized.

No its where all sub age 30 comp players are born, regardless of the game.

If you hit someone with the plastic water bottle with water from that lake, would that be assault?
Get out.

He also holds the world record of the most scientist-looking guy ever!
Me: pours salt in boiling water
Guinness world record: *NO.*
Thank you for sharing!
I also watched the playlist of videos on how the sample was collected. Brilliant work!
nothing is more salty than people on online multiplayer games
Very specific online multiplayer games mind you :3
: Online uno
Thanks for another fascinating video.
I recently returned from a trip to Israel, where I visited the southern Dead Sea. The water there is so salty that it is precipitating out large clusters of salts. The water outside the hotel I was staying at was literally carpeted with 4cm of these salt-spheres. Footgear was pretty much required.
It's nice to see you again professor! 😄 and we're almost a Million!

It is always a lot of fun watching your videos prof. Poliakoff. Спасибо!
круто!)
Great video. We missed you, Professor Poliakoff!
man , just found this channel and i love it!
Excellent video
Very interesting video!
You said that when you freeze the water you get no salt at all. Could you make a video of the water being frozen?
It would be really interesting to see the ice forming and pushing the salts to the top (especially since the ice would be transparent and the pure salts yellow!).
That would be amazing to see!
'Pure salts yellow' in the presence of iron, they are normally cloudy white or clear, unless there's unusually high mineral levels. High copper levels would turn the salt a blue or green hue :)
Edit: Nevermind, I think you mean specifically with this salt water sample :)
You are an excellent man, really enjoy your videos
I love this channel so much! I really disliked chemistry in high school and college but I'm sure if I had him as a professor I would probably be a chemist today!😮😅
I met the professor today and got to hold on of the dog toys that he uses in the videos and ask him some questions, I was going to a chemistry lecture so I was already excited but then I saw the professor and almost cried in excitement. I didn't even know that the professor was in Australia but this was one of the best days of my life!
The Internet has made it impossible for me to take the words "salt" and "salty" seriously anymore.
Horny Fruit Flies
And now for today’s word, moist! lol that one always gets me
Ok, then NaCl
Daddy
Great videos again,,
Happy to see your new videos prof sir martin,,
This guy is so nice
I am just happy for him because listening to him clearly shows how happy he is about everything he's doing
He's enjoying it so much
Sensation is usually log base 3, so double the salt concentration is less than twice as salty-tasting
"Ethiopia, in case you've forgotten, is on the east coast of Africa"

Great video
Can you do a video about mercury fulminate?
man grant thompson is doing so many collaborations with youtubers that have no correlation with his content im afraid that he will ask professor poliakoff to pour silicon into his hair and vaccum chamber it to "see what happens" lol
Don't worry, Sir Poliakov won't have that much free time to go to America.
(It's Sir, not just professor)
At the risk of being pedantic, he is Sir Martyn rather than Sir Poliakoff. Sir goes with the forename and Professor usually with the surname. His formal title is Professor Sir Martyn Poliakoff.
My guess is that he feels more like Professor Poliakoff than Sir Martyn. I'd be interested to know.
+sololight Um... he's called 'The King of Random' for a reason. Also, the videos, in which he puts something in the vacuum chamber to see what happens or the ones where he puts something in liquid nitrogen to see what happens, are mostly suggestions from his fans.
I wish Grant Tompson tried to see what happens when he went in a vacuum chamber without protection for several minutes.
Why the hate? Are Grant Thompson's videos not scientific enough for you? 8.4 million people seem to think otherwise.
Please make more videos as well as more often.
That video of the professor on the beach is totally epic!
...
well this isn't that video
It would make sense that taste would be logarithmic; as it is based on % of receptor sites filled.
Why does it make sense to you that it's not linear?
To me it makes sense bc hearing is logarithmic.
@@Baronvonbadguy3 so hearing is logarithmic, but taste should be linear? What?
Speaking of salt- One thing I would love to see a video about is the interactions between scientist and academic colleagues. Specifically, when have our profs and researchers clashed with colleagues (of course not asking to name names) in the professional environment? When did they handle it well and when did the not? Do they have some humorous anecdotes and suggestions for the inevitable friction in a field that is so remarkably social as science?
Since so many of them work in instruction as well, do they have some memorable classroom moments that seriously tried their patience? (I recall one professor losing his mind over a student watching UA-cam videos with the sound on and then lecturing him about his grammar when he asked them to stop.) I wouldn't want to stir any pots, but I am very curious how seasoned professionals in the field deal with those situations and ways they maybe wished they'd dealt with them differently. They can also make for some very funny, engaging stories in my experience so far.
Note to Sir Martyn: Juan (as in Don Juan Pond) is pronounced "Wahn".
Great video (as always).
I can't believe he didn't mention that not only is it the most saline, the pH of the water in these ponds in the Dallol Crater are around 1.0. Incredibly acidic!

Summoners Rift?
Explains the salt
I came to this video expecting the comment section to be full of memes...I was not disappointed :)
Very interesting!
Now that is an awesome tie
This man looks like science
Damn water, why you so salty!
That tie is awesome
Gosh, I am far from being a Chemist myself, but boy, do I enjoy these videos.
"This sample might not look like much"
Dude. It looks like bottled urine
No wonder it’s so salty
But isn't the water mostly hotter because of the vulcanic activity and not because it's closer to the equator?
yes but compared to the to the freezing weather of the poles, being in the equator by itself is much hotter
Antarctica is also volcanic.
quite..
The difference is that the surface of the Antarctic pond is cooled by the Antarctic air.
I love your videos! Your hair is amazing too
love u, My chemist's einstein prof 😍
Ahh the gaming drink of rainbow six siege players
Entertaining video but shouldn't the pond (that's no lake) be said to be the world's saltiest known lake? The previous record holder had a very short reign. The Ca and Mg salts are substrata and the Na salts are often surface deposits. Any theories why? Associated with planet formation, I suspect.
The Calcium and Manganese salts in this body of water come up from deep down with the boiling water feeding the lake.
Captain Duckman. Yes, that much we know. How did it happen that sodium salts are generally formed on the surface and then, perhaps buried, whereas calcium and magnesium salts are generally subterranean? My wild guess would be heat driven disassociation of calcium and magnesium ions at volcanic temps. Sodium (from group 1) hangs on to the fluorides more tenaciously. Volcanic lakes are generally not K/Na salted.
I love taht he is so humble about neing a chemist.
It makes so much sense to me that he makes vids, very interesting, shoe fits for sure lol
So this is where Reddit's saltiness comes from! No wonder they call it "The Fountain of Infinite Salt"
Salt in sea water is mostly NaCl, but this isn't. Why? Where did all that sodium and chlorine come from in the oceans?
Ray Kent soil composition, rock salt
sailors' tears when finding out that manatees are not as attractive as the mermaids they thought they were seeing.
CaptainDuckman they can still diddle the fiddle with a manatee
Ray Kent whale semen
Most of the calcium and magnesium in seawater combine over time with carbonate (CO2)from the air, and precipitate as limestone and dolomite rocks (the White Cliffs of Dover). Sodium and chloride ions are always soluble, do not precipitate readily, and keep accumulating in the sea.
Great video, it just answers a question some of us had, but what if the water was nearly the boiling point, can more solids be dissolved in it?
Yes
That's a dope tie
I can bet you my liver that that water isn't as salty as my ex
DAMN
but your ex is not a kind of water.
Legends say that iwdominate is made of this water
Helpful Guy such memes, much wow
"unless taste is logarithmic" 😂
Gotta love that one
Can you please do a chemistry analysis of the Salton Sea... and the repurcussions of living here now and living in the future after the sea completely evaporates...
At first glance, I thought this was a video about Overwatch players.
You're wrong, it's about League of Legends players.
Oof
Nah overwatch players are way more toxic lol
there are still OW players?
You can find saltier substances. Go to fortnite and cod modern warfare game lobbies.
That's heavy man.
i love how he explained damn tara
You said the lake is 2x as salty as the dead sea but in the stats at 5:27 you can see it's only 25% saltier than the dead sea.
tennisdude52278 nice eye
logarithmic?
There are two different ways of measuring dissolved solids: 1. Grams per liter of solution. 2. Grams per kilogram of total solution (solid plus liquid).
As the concentration of dissolved solids increases, the amount of liquid reduces, and at the same time the density of kilograms per liter changes. At high enough concentrations these two number diverge substantially. Perhaps The Prof also misspoke (never!)
Ghost Hunter I think you mean to say "logarithmically" not "exponentially." And concentration does not increase logarithmically so that can't be the case.
Gordon Richardson The amount of liquid would only reduce if solids precipitated out. The amount of liquid would not reduce from solids dissolving in it.
It formed on Novermber 8 , 2016.

A challenge for Periodic Videos followup: Get your lab mates to come up with the "saltiest" lab-artificial solution as a comparison of what is possible. The criteria seems to be highest g/kg in aqueous solution. That means there is no restriction on the elements that make up the salt. Good luck!
I remember (somewhat vaguely now) super-saturated solutions in chemistry at school.
The comment section is much saltier than the lake...
And your one of us
Not saltier than my ex
Finally a mildly funny salt joke.
Anything planned for the millionth subscriber? I know from HI that Brady isn't that interested these days in sub milestones, but a million is the big one.
Imagine being stranded in the desert for days with no water. the sun is roasting you and you finally come across some water only for it to be this boiling cauldron of salt.
Looking for the worlds saltiest water? Just look no further that the League of Legends community...
Title: "World's Saltiest Water"
Sir Martyn: "There is no salt in the water"
*I'm sick of the lies*
Great, now I'm going to collect water samples from everywhere I go.
Oooh maybe I can use some local water bottles to do it. ;)
(I'm on mobile)
I tapped on this immediately when the notification showed up.
why is the position of the pond in ethiopia near the equator relevant when it's fueled by a volcanic source and not the sun? Even if that exact pond were in siberia, it would still be more salty than the one in antarctica.
One could say that heat would dissipate from the water quicker in a location where the surrounding material is colder. That the lake in antarctica has more trouble keeping it's temperature. (assuming the body of water is big enough that the source of the heat takes some time to warm the water.)
I think that's because when the water reaches the surface it may cool down quicker and not have as much salt in it as it has on the equator. Being in the center of Africa helps it to keep the temperature higher.
Or I may be completely wrong on that one as it is just a guess
It's like tumblr.
Deep ocean brine pools are also a fascinating phenomenon that have 3 to 8 times the salinity of seawater, While being underwater.
You read my mind. I DID want to know how it compared to the Dead Sea.
All the unfunny salty jokes
