    Considering that water autoionizes, yes - it is both an acid and a base.

      Inclusive or

    “I’m whatever you aren’t, you fucker” - water, to the substance you mixed with it.

    Little bits of it oscillate between hydronium and hydroxide so a little of both but not enough to make a difference.

      That’s why the meme works. It’s not because water autoionizes; it’s because water is amphoteric, meaning it can act as either a Brønsted-Lowry acid or BL base depending on what what it’s reacting with. Put water with ammonia, and water acts as an acid. Put water with acetic acid, and it acts as a base

        Water is so cool. I like how the hydrophobic effects drives protein folding

        Not really. Deuterium exists naturally in more it less the ratio as it has since the solar system first coalesced.

        Also, deuterium is a component of heavy water, but the term “deuterium” actually referred to the specific isotope of hydrogen where the nucleus consists of one proton and one neutron, as opposed to a single proton (which is the more common isotope)

    Yes

    H2O is neutral PH, and so answer is no. But then water tends to have a bunch of shit disolved in it. So answer is yes.

    A self-contradicting proposition based on ambiguity of definition of water, of all things. This statement can be used to make HAL explode.

      If you take into consideration the self-ionization of water, it’s both, at the same time.

      2 H~2~O -> H~3~O^+^ + ^-^OH

        AFAIU, it doesn’t change the PH neutrality.

        I understand that they self combine/react again? But is that reaction still water?

      It’s not neutral, pure water is slightly acidic due to free hydrogen

    Ah yes amphoteric compounds

    Do you mean dihydrogen monoxide?

    • mmddmm@lemm.ee ⁨3⁩ ⁨weeks⁩ ago

      Pretty sure the OP meant hydrogen hydroxide.

    What is the PH of the water? 🤔

    source
    • spicystraw@lemmy.world ⁨3⁩ ⁨weeks⁩ ago

      About 7. Fun fact i did not know before research, at 100 C waters pH can go as low as 6.14.

    It is the final frontier for either, your meme could have been so much more interesting. SAD.

    Isn’t water itself the pretty literal definition of 0 and it doesn’t become one or the other until it’s a solution with something else?

    source
    • joyjoy@lemm.ee ⁨3⁩ ⁨weeks⁩ ago

      Water is the definition of 7.

      source
      • CookieOfFortune@lemmy.world ⁨3⁩ ⁨weeks⁩ ago

        Also I’m pretty sure it’s only coincidentally 7. The calculation for pH isn’t based any property of water.

        Right, whatever the midpoint was. It’s been a minute since my last chemistry class.

    • trolololol@lemmy.world ⁨3⁩ ⁨weeks⁩ ago

      But is it +0 or -0? Neutral 0 is a lie, a measurement precision error.

    Is this about the anomaly of water? I vaguely remember it from school

    source
    • Una@europe.pub ⁨3⁩ ⁨weeks⁩ ago

      No, this is about water being amphoteric compound meaning it behaves like a acid or base in different circumstances.

        The water molecule is amphoteric in aqueous solution

        A water molecule in aqueous solution. How can you tell it’s being dissolved, or doing the dissolving?

        You mean it lives on land and in the pond?
