    My theory would be the intense heat somehow loosened the ionic bond and caused the sodium to act independent of the chlorine in reactions. Then, while our friend sodium is making hydrogen with water, and that causes the chlorine(a poisonous gas) to be left behind. Both gasses being heavily heated up by the absurdly high temp of the salt, but deprived of enough oxygen or hydro carbons to start a real fire, the gasses expand in a weird, semi combustion reaction. That was just what I thought. I’m not sure if it’s true or not or even if they explain it as I haven’t finished watching the video yet.

    Like oil, sodium chloride is slightly hydrophobic, meaning it doesn't mix with water very well, and water suddenly boils when something extremely hot touches it, so, my hyothesis is that the water and salt are repelling each other, amplified by the water boiling in the presence of the extreme heat of the salt, as well as the salt suddenly cooling. The same effect can be achieved by mixing hot oil with water (don't try that at home).


    What salt is neutral . Why are testing it's ph

      its not that, its probably that a different solution interacts differently with other substances. It s not that it cools it down faster, its that those extra ingredients suppress or maybe even diffused the explosion

    It could be that the salt explodes and the others dont because of the consistency of the liquid as it enters the water, the salt was extremely fluidic whereas the other liquids were more viscous. This also adds even more evidence of a physical reaction.

    I think I know what is happening here but I am no scientist just a theory.
    I thin since you melted the salt it detaches/dissolve the chloride from the sodium and when you toss it in the water it’s so hot water can’t touch it but it cools so fast i has time to get in there and then explode rather than sink to the bottom because the other metals stayed hot longer.

  • Rett Williams

    So my hypothesis is that the sodium is reacting with the water in the way it normally does, but the chlorine is causing a slowdown of this reaction. This reaction combined with your leiden frost description explains why it works well with NaCl but not other "ionic compounds ". The PhH doesn't change because both molecules of Na and Cl are still in the solution. The reason this doesn't happen with non melted salt is because, well it just doesn't. This is just my thoughts and I only have your data since I'm like still in high school

    Crystalline structure of NaCl has nothing to do with the explosion and neither does sodium metal play a role in the hot liquid sodium chloride explosion.
    Note that if the hot liquid sodium chloride somehow converted sodium from its +1 ionic state back to sodium metal (a reduction process), then the contact of the sodium metal would create a flame like the hot liquid sodium metal does when poured into the water. Note that room temperature sodium metal tossed into water also causes an explosion with a flame. The sodium metal reacts with water and dissociates water into Hydrogen gas and the sodium becomes NaOH. This chemical reaction is strongly exothermic and releases large amounts of energy, igniting the released hydrogen gas product, that further burns and chemically reacts with oxygen in the air and releases even more energy and gas, contributing to the explosion. The liquid sodium chloride explosion with water is missing the flame and therefore we can deduce the creation of sodium metal isnt the mechanism.
    The video guy says it's not a chemical reaction, it's a physical reaction and hes correct. The hot liquid sodium chloride has a very large heat capacity and the rapid heat transfer properties of hot liquid sodium chloride transfers energy so quickly to the liquid water that the water instantly boils on contact. It's the RATE OF HEAT TRANSFER that is key to the explosion. Common to all explosions is a rapid density change from a solid or liquid to a gas and its the same with liquid water rapidly converted into gaseous steam. The instantaneous density increase creates the explosive density change and in a few cases is enough to break the glass.

    the sodium chloride reaction is physical. when it is done, you still have sodium chloride and you still have water, but in its gaseous form. When you dumped the pure sodium into the water completely different chemical substances were being formed. (probably sodium oxide and pure hydrogen which was ignited when it reached the surface to create water again). Therefore the second reaction is chemical and I believe would have caused an explosion even if the pure sodium metal had not been molten, but without the added fireworks due to the hydrogen explosion at the surface.

    Haven't you seen how Na interacts with H2O? I believe all your experiment based on it. In case of salt (NaCl) and temperature you got kind of free Na there I guess.

    Technically what I'm trying to say is that your sodium causes a surface blast and then your melted table salt causes a concussive blast two different types of blasts concussive is disoriented and could be the cause more damage internally than it does in the outside whereas the surface blast causes more damage to the surface but barely any to the internal organs my brother was a bomb technician in the Marine Corps I was a Army Ranger

  • Kimberly Herlinger
    Kimberly Herlinger 9 days ago

    You getting two different types of blast brother the blast that you got from the pure sodium is a surface blast and that's perfect for calling damage to surface tissues blowing things apart burning things something like that where is the result the chick getting from the salt that would be something that you would use it like like using it in the water you wouldn't catastrophic the crush the organs of any creature that was nearby that reaction

    Maybe the explosion is the same thing that happens with boiler and Coke can explosions?
    When a boiler bursts or a coca cola can is pierced with a knife or sharp point the presurised molecules directly by the first tiny crack/piercing of the metal escapes and expands in open air and in the boiler/can the surrounding molecules are suddenly free to expand...and the surrounding molecules can also expand...in a very rapid chain reaction with very high pressure and 1600 times expansion which we see as boiler explosion of coke can explode.
    Maybe the blob of molten salt is doing the same chain reaction as seems to be shown by the continuing expansion and eruptions as salt molecules can expand without limit until they have all expanded to their maximum and also been cooled below their eruption level?
    The molten sodium hitting water is more a simple heat explosion.

  • Wendy Letman
    Wendy Letman 11 days ago

    The salt gets water inside it and then the water burst out of the salt. The water makes the salt flood up so fast that it just goes crazy when out in the air. Ya know the video where ya pour molten lava in ur pool. It might be like that but the salt dries up so fast it explodes. IDK
