Just another personal anekdote:
A friend bought a water destiller because of some health-theories. You are supposed to drink distilled water in the morning and so on... He is usually using it on tap water because he believes the water isn't pure enough (Germany, should be pure enough). One day he figured he could try the bottled water, maybe less build up of chalk in the sistern. This area has a lot of chalk in the ground so everything gets white very fast. He was not totally surpriced with having a black burned, smelly gunk in the bottom the next day. He does not buy bottled water any more :-)
- samcheng 7y agoDistilled water, particularly if heated, is dangerous to drink, according to some chemists I know. The concept is that the ultra-pure water leaches potentially harmful ions from its surroundings, for example chromium from stainless steel fixtures. Better to drink some harmless sodium and chlorine ions.
- discordance 7y agoI think you're referring to deionized water. Deionized (DI) water is water that where all ions are removed. This is not safe to drink. Distilled water is boiled and recondensed water, which leaves you with pure H2O (no minerals etc). It's safe to drink but pretty bland.
- dwighttk 7y agoOutside of hydroxide and hydronium, which ions are left with “pure H2O (no minerals etc)”? And DI water gets hydronium and hydroxide pretty quickly (if they ever go away.) H2O just breaks down into OH- and H3O+ on its own (as far as I know)
- hollerith 7y agoI agree: in fact the deionization process adds one hydronium or hydroxide for every (mineral) ion it removes: >Deionization is a chemical process that uses specially manufactured ion-exchange resins, which exchange hydrogen and hydroxide ions for dissolved minerals https://en.wikipedia.org/wiki/Purified_water#Deionization https://en.wikipedia.org/wiki/Purified_water#Deionization In other words, if deionized water is unhealthful because of a lack of ions, distilled water is, too, because it doesn't contain any more ions than deionized water does.

- lightgreen 7y agoReverse osmosis devices include mineralization filters, which add salts to nearly-distilled water.
- samcheng 7y ago"RODI" (de-ionized reverse osmosis) water can be as pure as distilled water, and is common in labs. I'm told you don't want to drink the lab-grade stuff.
