Margarita Salt wrote: Please, don't dole out information when you don't know what you're talking about. Spring water is spring water, distilled water is distilled water. Spring water is not "purified" distilled water. Distilled water does not have an odor, nor does it have anything else. That's why it is recommended for steam irons, humidifiers, vaporizers, etc., so the evaporation doesn't leave behind lime scale or any other mineralization to corrode or clog the systems. It's produced by condensation or evaporation. No, Hon, distilled water is produced by distillation. Evaporated water disassociates into hydrogen and oxygen molecules and condensed water isn't necessarily distilled water. If you are going to nit pick, at least be sure they are nits. -L. (snickering) don't snicker too much, distillation is evaporation and condensation, yuk yuk. you can see this for yourself. take a pot of water and boil it. in a way, crude way, you can say the water evaporates or become steams onto a glass lid. if you tilt the lid, the water condenses on the lid and is distilled water. that's all a distiller does. creates steam, think vapor or gaseous thing here, and then allows that steam to collect or condense back into the liquid form. |

I had to go back to tap water to stop the epidemic. get a flouride treatment from your dentist. it's a gel placed in the mouth for so many minutes or whatever they do now. i gather you need flouride to protect against cavities then? Because we like the cats to get pure water, we've been using a product for them for years, when a vet recommended it. Oxyfresh Pet Oral Hygiene Solution. Seems great for the teeth, the vets never find much tartar or any real tooth problems. Some vets carry it, or you can buy it on line. It's 5 mL per "quart (1L)" [sic] of water, so we just put 20 mL into a gallon of distilled water and fill the bowl as needed. is this a hydrogen peroxide product? interesting, i'll check it out. i hope it's not hydrogen peroxide which can possibly attack enamel if you're not careful. it's a great killer of germs but i'm worried about its long term effect on enamel. does it list the ingredients? could you list them here? i don't see them listed offhand on the 'net. |

It's not even midnight here, Bar. I am a West Coaster, remember... interesting i can't imagine anyone setting up at this hour posting anything Setting what up? Do you mean "sitting up"? Late PM is the only time I have to myself, when my "guys" are sleeping. I get all my housework done at night too. But because of this, I require a siesta. Go get your woobie and lay down on your beddie-bye. I will be in to tuck you in, in a minnie... -L. |

wrote: i missed your disassociation. that's not evaporation. that's electrolysis. The molecules DISASSOCIATE into hydorgen and oxygen. They do not. Evaporation does not cause disassociation. This is a completely wrong comment from you. Again, evaporation which you stated has nothing to do with disassociation. Evaporation is just going from a liquid to a gas, but the molecule is still the same molecule, a water molecule with 2 hydrogen atoms to 1 oxygen atom. It's 2 hydrogen atoms to 1 oxygen atom because of the valence of oxygen. Valences originally came from Linus Pauling who received the Nobel Prize for this observation. His first Nobel Prize. The second was the Peace Prize. And he was close to a third Nobel for DNA but lost out by probably a matter of months. No one else has come close to three Nobel Prizes as far as I know. With me so far? Linus Pauling aside, evaporation is just a state change. If you wish to disassociate, you need a process like electrolysis which separates the atoms in the water molecule H20 into the very different gases of hydrogen and oxygen. At that point, it's obviously not water at that point, and is, in fact, two separate gases that are not water vapor. But evaporation, again, does not do this. Evaporation keeps water as water. If evaporation allowed disassociation, we would have free energy, just about, unlimited quantities of hydrogen gas for fuel without any effort but allowing the sun to evaporate the water. We would also have extremely large quantities of the explosive gas of hydrogen. Another reason that your comment that evaporation is disassociation is just plain wrong, wrong, wrong. More than wrong, does not make any sense. If water evaporations caused disassociations, the entire earth would become a ball of fire and be destroyed. In other words, our entire planet would be cooked if you were right in your assertion that water disassociates from evaporation. The earth is not being destroyed because water evaporation of the oceans just causes the liquid water to become water vapor in the atmosphere where it condenses back into a liquid like rain and so forth. Where on earth did you get the idea that evaporation causes water molecules to disassociate? I am really curious. Was that a high school chemistry class in which you were nodding off? Now before you argue with me, just look this up in Wikipedia.com Let me guess - you read the ad on your water bottle... -L. That's a start, you need to read the label on the bottle, how else do you suggest starting? No label, then who is the manufacturer or supplier? Then you contact the manufacturer and the state's labs and go from there. The manufacturer and the state will send you the anaylses. You can then compare them to see if they are the same, or in the same ballpark. Then you can compare the analyses with what the EPA puts out as guidelines. This is just the beginning but a good one. It's enlightening to see the errors. The first time I did this, I pointed out to the state that their tests for lead, the minimums, were much higher than the EPA levels. In other words, the water could be contaminated but it would not be known because they set their lab standards incorrectly. To which the state lab replied, oh. |

Boiling water doesn't dissociate. You've got to heat steam well over 1,000 degrees C to get even a tiny amount of hydrogen and oxygen. -- The night is just the shadow of the Earth. |
