    Fun fact; cats can drink straight seawater. Mad good kidneys or something, so the soup is going to get far too salty for a human before it gets too salty for a cat.

    It is the other way round though isn’t it?

    Sodium Chloride is just chilling as a rock or in suspension and then humans put a lot of energy into it, so it is forced to separate. Imagine you and your spouse being torn apart with a lot of violence.

    Of course you get traumatized and act out until you get reunited and have some time to become chill again.

    This is how the Karens and Mommy Blogs sound when they complain about “Mercury in vaccines” but it’s just one mercury atom in a molecule that no longer behaves like elemental mercury

    That’s one thing that annoys me about lithium batteries. Every time there’s an EV fire, people pop out of the woodwork to shit on the FD for using water to put it out.

    Just because the name has lithium in it doesn’t mean it’s elemental lithium.

      It’s a situation of just enough knowledge, I think. It’s true that water won’t put out an EV battery fire, but it will cool it down and prevent the fire from spreading.

        Well, it will put out the fire, but it does it by cooling the battery down so the reaction stops (like you said)

        I guess it depends on what burns. Water is conductive, so you might not want to use it to put out an electrical fire because of the risk of electrocution.

          A lithium battery fire is a chemical fire, not an electrical one. There’s pretty much a zero percent chance of getting electrocuted putting one out with water.

      On one side of the battery, it is elemental Lithium.

      It exchanges electrons across a membrane with another substantial.

      Using water on it is bad because the reaction between Lithium and water evolves Hydrogen gas, which ignites in the fire.

        You’re wrong.

        Lithium batteries contain little to no elemental lithium. They normally contain lithium cobalt oxide, lithium iron phosphate, or lithium nickel manganese cobalt oxide as the anode, and a lithium salt as the electrolyte.

        Water is about the only way to put one out because it’s an exothermic reaction (water is to cool it down so it stops), and two out of the three are self-oxidizing so you can’t just smother it.

        The biggest danger of a lithium battery getting wet is that it shorts, which can lead to a fire because it goes into thermal runaway. But this can happen if you have one in your pocket with spare change (most of the vape fires in the 2010s were this)

    Even just H and O on their own can be quite scary. Throw them together and BAM, ubiquitous lifegiving liquid.

      I know you wrote H and O, and not H2 and O2, but I’m going to assume the gas forms because those two substances pretty much cannot exist in their pure forms

      And for those, O2 is necessary for our life, and H2 is non-toxic, it’s just very flammable. So I don’t know if the comparison fully works

      Of course, you’re right if you mean pure H and pure O, but, again, they will immediately combine to form a new substance

    Salt is scarier than the elements sodium or chlorine because, according to Wikipedia, “Salt is essential for life in general.” Without salt, there wouldn’t be humans creating things like chlorine gas. Life is scary.
