I wish I had this video back in my IGCSE days cause I had a HARD TIME with electrolysis

[@arkzbh]

I did the experiment as a 7th grader, took a bowl of water, added a couple of handful of salt. Then took a power cable, sliced off the plastic from both sides, attached it to the wall socket in one side, dipped the other side into the bowl, and then... turned the switch on. 😃 A big and very brief "brooop" sound, felt like a shockwave, all the water disappeared at once, and no electricity at home for several hours 😂 Turned out, the main fuse saved the neighborhood by dissolving itself for my incompetence 😂 The only good thing I did that day was, not touching the bowl while I turned the switch on. In that case, I wouldn't be here, alive, to write this. So, kids, please do not do this without having an adult to supervise your work.

[@PankajGupta-hr8iq]

Not necessarily you would die from it, but still its better anyway that you didn't suffer the shock...

Sounds fun, do it again and film it. Post it on Tiktok with some challenge and watch neighborhood blackout in random countries.

idk what kind of sockets you have (/had) but 220-230V wont kill you, it will barely scratch your skin. I've been electrocuted by wall socket several times and nothing really happened to me. Tbh I've electrocuted myself on purpose a few times cause I like the feeling 🤣

The hydrogen molecules in water are at 104.5 degrees from each other, not 180. This is a consequence of the electron configuration and how the valence electrons are shared. This angle leads to water being a polarized molecule with the hydrogen atoms being electropositive and the oxygen corner being electronegative. This polarization gives water its many exceptional properties. It is a good solvant, has strong surface tension, and a wide range of temperatures at which it remains liquid. These facts make it essential to the existence of life.

[@Kalumbatsch]

Did he say anywhere that the angle is 180 degrees? Didn't think so.

[@Maninawig]

This year I saw how audibly harmful adding oxygen to helium is, or liquid oxygen to carpet is as it supercharges the ability of something to conduct flames. Though I studied a fair bit about hydrogen, I never put it together... 2 parts flamable gas to 1 part accelerant makes a vital liqiid to survive and one able to quench flames... That sounds quite the contradiction

[@Kalumbatsch]

Sorry, what?

[@Maninawig]

@@Kalumbatsch adding oxygen to a helium balloon and lighting it makes a loud boom. In a mega balloon, it can cause ear damage. Hydrogen motors are dound much safer as the tanks are way more resiliant than a car's gas tank. And when damaged, they leak back into the air, disipating to an oversaturated amount, unlike gas that pools under the car and can make the car explode. That said, a hydrogen balloon will explode with a spark or flame. Oxygen makes burning materials burn much more efficiently, as it feeds the flames. Liquid oxygen on carpet, when added friction, will make the carpet burn up in seconds. Anything else confusing?

[@Kalumbatsch]

@@Maninawig "adding oxygen to a helium balloon and lighting it makes a loud boom." No, it doesn't. Helium is a noble gas, it doesn't react with oxygen. You're confusing hydrogen and helium.

[@Maninawig]

@@Kalumbatsch you are right in stating that helium cannot molecularly bond to oxygen if a balloon was diluted mixed 50:50, the same would be said with Hydrogen, as they would require additional physical reaction to seperate the stable O2 into O1. However, what I am talking about isn't related to molecular bonds but chemical traits of the elements. Both hydrogen and Helium share the trait of being flamable. In other words they go BOOM and the flames are born. However, Oxygen is not flamable, but it is annoxidizer. In other words, it won't light on fire or go BOOM, but it does make flames brighter by feeding itself to the flame. Thus, by having a balloon mostly-filled with any combustable gas and partly filled with an oxidizing agent (oxygen being the purest form), then your boom is amplified. If you are referring to the Hindenburg, then it's important to know that the same thing would happen if it was filled with helium... The problem is that the painter chose to ignore the warnings and use a cheaper paint that, with the movement of the blimp, created enough friction to spark a flame.

[@Kalumbatsch]

@@Maninawig "Both hydrogen and Helium share the trait of being flamable" No. That's bullshit. It's 100% wrong. Helium doesn't burn. As to the rest of your word salad, you have no idea what you're talking about.

Hydrogen is liquid only at very low temperatures. Oxygen is only liquid at very low temperatures. But when you combine two parts hydrogen and one part oxygen, you don't need very low temperatures for it to be liquid. Weird, huh?

[@Rick-the-Swift]

2:20 I wonder what would happen if instead of putting opposite electrodes of a battery into the salt water, we instead put the positive and neutral terminals from a wall socket? I think I might have to try this at home :)

[@cyclenut]

That would be VERY dangerous. I used a 12v car battery. it will produce enough voltage and amperage to separate the atoms a pretty fast rate.

[@williamhrivnak7345]

I’ve seen versions of this experiment where they actually harvest the hydrogen gas and create a mini fireball with a match, but you would need to do a lot of hydrolysis and waste a lot of batteries to get enough H2 for an engine

[@HxTurtle]

to put in some more thoughts at the around minute mark where he adds salt to the water (to "ionize" it). to put it very shortly, bluntly, and probably with too low a sophistication: water dissolves metal, metals so conduct electricity quite well (contrary to just water alone). therefore, water that comes into contact with metals becomes conductive. your tap water at home is already quite conductive (as opposed to pure rain water) because it already came into contact with various metals. this night not be totally obvious at a first glance, but our very surface essentially consists of metals. what you tend to call rock, I dare to also call a metal. way more than you think is actually a metal, and so is salt. since we humans adapted to drinking water, we now even need those extra parts in it (which in this case, we then call minerals .. but again, essentially another word for just yet again the same, namely metal). salt is a metal as well (when it dissolves in water, it's quite safe to call it a metal. sugar isn't one, but it only dilutes in water; not dissolves). he only adds the salt essentially to make extra sure the water will be conductive enough for this experiment to succeed (which I haven't seen yet, but can somehow imagine what it'll look like, lol).

[@AdroSuperDopa]

How come car engines don't run on hydrogen? Maybe we just full the tank with water and it would just exhaust oxygen.

[@kinnikuzero]

They actually exist, but it's not that simple. The car has an electric cell powered by hydrogen gas and a catalyst cell. The hydrogen tank has to be huge and takes a big portion of the car, so it's not very practical. Also having a huge pressurized cylinder on you the whole time might seem intimidating for many

[@ThumpertTheFascistCottontail]

It doesn't work because the amount of energy you need to put in is about equal to the amount of energy you would get out.

[@otakuribo]

Hydrogen fuel cell cars are totally a thing! They actually exhaust water, because that's what you get when you react hydrogen and oxygen, but yeah, they're a thing! en.m.wikipedia.org/wiki/Fuel_cell_vehicle Or at least, they could have been a thing. The problem is getting elemental hydrogen in the first place. Simply put, it takes much more energy to break water apart than what you get out of it when you put water back together. So either you eat up a LOT of power at the factory to produce hydrogen by electrolysis (the process Rob demonstrated), or you use hydrogen that's produced as a byproduct of natural gas refinement. Neither of those options are very sustainable or environmentally friendly... That is why the industry* has focused in more recent years on making better batteries so electric and hybrid-electric vehicles can be more viable options; together with addressing the way we produce electricity. It's not just cars that are burning fossil fuels and contributing to climate change; it's the power plants, too. So the hope is to transition to cleaner energy sources like solar, geothermal, biofuels, wind, and maybe even sustainable fusion reactors within the next decade or so! It's something to get pretty excited about! *I am, of course, referring to sensible side of industry that wants to keep living on a habitable planet, not the greed-driven oil companies and political interests that are actively fighting against this kind of progress

So why isn't water flammable? If it's made of hydrogen and oxygen it should explode when in contact with a flame. We should be able to put it straight in the petrol tank and go. Why can't we?

[@keithwatson8228]

So if the oxygen is dissolving back into the water, and water require quite frigid temperatures to maintain a liquid state, that liquid oxygen should be cold.

[@carneeki]

The water doesn't need to be cold. The dissolved oxygen is how fish breathe, so think about a tropical river with warmer water, the fish can still breathe it, and the water is not frigid. Liquid oxygen is certainly very cold, but the oxygen that is dissolved in water is not liquid oxygen, the same way the table salt that Rob sprinkles in is not a liquid either, rather the molecules of sodium chloride (the chemical that is table salt) are separated and spread around the liquid being held in place by similar electric charges to what Rob describes with the battery terminals. Solvation is a quite detailed topic, I'd suggest reading about it on Wikipedia as a start, and if you are really interested, borrow a high school chemistry textbook from a friend or library to learn more about solutions, solvents and solutes.

[@keithwatson8228]

@@carneeki the fish breathe through osmosis. Water is oxygen combined with hydrogen. Pure oxygen can not maintain a liquid state above -119 degrees Celsius. You should research before you correct someone. Otherwise you just look dumb.
