Water: more oxygen, better taste?

    Sometimes we run out of bottled drinking water and I just boil tap water for drinking
    but I hate the taste.

    My dad says if I leave the newly boiled water uncovered for a while, it will recover its (fresher) taste.
    He says that's because the water got oxidized while boiling.
    wtf does that mean?


    (I can't ask him a question without sending him into a lecture about my 'expensive' education so I didnt ask)

    One of the two of you is misunderstanding something VERY basic. First off, you cannot oxidize water. Second, the *real* problem is that you have forced out all the dissolved gasses in water when you boil it and that's why it tastes "flat."

    And yes, allowing it to sit (for a LONG time!) will make it taste better because it will slowly re-absorb the gasses from the air.

    Ok. Maybe I misheard him...I am wondering now.

    The water doesn't just taste flat, it acquires a taste that I can't describe...something near to pungent. The tap water it came from tastes much better.

    A long time as in more than 1 day / is practical? So I cannot actually apply his advice? OK I believe you but Im mystified - it's unlike my dad to give impractical advice.

    Is the taste like chlorine? Boiling will not remove any minerals, it just kills bacteria, so maybe in the process of making it sterile and flat, the taste of the other things is enhanced somewhat.

    You can aerate the water faster by agitating it to expose more to the air, like pouring it between two containers or bubbling air through it. Shaking it may work some as well...don't know how long you'd have to do it to get the flatness out.

    Just put in a bottle and shake it up.

    btw it does taste a bit like chlorine come to think of it.

    100% pure water has interesting qualities. It's toxic to drink and has a slippery feel like soap.

    Probably subjective, but i've never felt any tactile difference between pure water and tap water. Not even in the mouth. It tastes horribly bland though.

    Where in the world did you dredge THAT up from? Toxic??????:bugeye:

    Too much water will kill you. It's also very corrosive to some substances and an oxidizer.

    You probably never encountered water that was pure enough. I worked at a lab that re-distilled one large tank of water constantly.

    A scientist. It removes electrolytes and minerals from your body. It can lead to heart irregularities.

    You totally can oxidize water. It's just not water anymore after that though.

    Delt with pure water (I.E. 18 mega ohm analytical grade deionzed but you can never, ever get it pure) and does not feel any different (maybe a little lighter feeling but thats about it). It is also not anymore poisonous than regular water. I get it on my hands and what not all the time.

    Deionized water isn't distilled.

    BULL !!! You best ignore that so-called "scientist" from now on. Certainly, distilled water is demineralized - but that hardly makes it TOXIC!!! A toxin, by the way is a poison.:bugeye:

    As to those minerals and electrolytes, the VAST majority of them in your diet doesn't come from drinking water. So on that truthful basis, your "scientist" has struck out twice in a row. Pitiful !!!

    True, but the 18 mega ohm resistivity should have tipped you off that it is distilled (actually in this case filtered by a fancy ass setup but the results are the same/better because you don't get the dissolved gases/volatiles when you filter it), then deoinized.

    Maybe you should not be so quick to talk. Spider was talking about it washing away the electrolytes that are already inside your body (which regular water does as well, try drinking a gallon and a half in 45 minutes and see how you feel. Actually don't because if you do and pass out from it the symtoms of over hydration are about the same as for heat stroke. Since heat stroke is more likely they will fill you full of I.V. fluids which will kill you.). No one was saying that you get any nutrition (except for the water itself of coarse) out of the water.

    Bear with me, I'm not a scientist, but that distilled water felt slippery. It also wouldn't boil.

    It would boil unless you had a perfectly smooth surface on the glassware you tried to boil it in. Then it has no site to nucleate to form bubbles (even with the smooth glassware this is normally not a problem because it can nucleate off the dissolved particles). It's really fun to drop something into it when it's in this state though because it all boils at once!!!

    Slippery..... maybe had something on your hands?? I've noticed that it tends to stir up surfactants (sort of soap cuz it makes bubbles in the same way) more than normal water. You could have had a small amount of soap left on your fingers from the last time you wash your hands (but not enouph to normally feel) that was re-slippyerized (not a real but it works lol) from the pure water.
