in very small trace amounts = good for teeth? kills certain germs?
yeah some guy said, that its used to enrich uranium, for nuclear weapons, and to prepare serin nerve gas.

And oxygen is a catalyst for fire. We still breathe it.
No excuse that.

I don't drink tap water (but I do drink alot of water)
I sound like such a ponce, but there you go.

Meh i drink tap water all the time don't give it a second thought.
I have lived my entire 19+ years of existence in a city without a fluoridated water supply.
I have never used fluoride regularly... only when I visit the dentist.
I have never had a cavity, never chipped a tooth, never needed... any serious dental or orthodontic work.
*knocks on wood*
But really... leave the fluoride out of the water. I, personally, would not raise children on a fluoridated water supply.

When i lived in oz for the first 4 years of my life the water had fluoride in it.
It bsically made mine and my sister's teeth bright white,never had any problems drinking it though...

Many specialty mouth-washes use Fluoride in their product. My orthodontist is constantly reminding me to always buy mouthwash with Fluoride in it - it low doses it protects the teeth. A must for braces, also
Tbh a catalyst is a substance that can speed up a chemical process without beeing consumed itselfelbekko wrote:

Oxygen = fuel for fire
Your thoughts, insights, and musings on this matter intrigue me
It's good, but of course too much of anything will stuff you up. This is one reason that toothpastes tell you not to swallow the foam.
Is there more flouride in tap water in the US than Australia? I think I read that somewhere.

Fluorine can cause some illnesses for some people. (don't know the names of those though, but I've had one as a kid)
Would really want it in my tap water. Good thing is that we have the cleanest water in the world in Finland, and AFAIK there is no fluorine added.
They even use chlorine in water in the US and some other countries.

I don't think bottle water is any better than tap water.
Melbourne's water is pretty bad (like drinking pool cleaner), I would hate to think that statement were true.some_random_panda wrote:

My state was founded by Batman. Your opinion is invalid.
most bottled water is tap water, where did you think it came from lol , right out of the stream????loubot wrote:

That man knows nothing of chemistry, or he'd know that all chemicals have multiple uses, and vastly different properties depending on the compound.
Your teeth (dentine and enamel) are made up of something called calcium hypaxate (something like that) which has a solubility constant of the magnitude 10^-50, which means it is very hard to dissolve, however when exposed to acidic environments, it becomes much easier. When fluoride is added to the water, the F atom displaces an H atom and increases the solubility constant to the order of 10^-60, which means your teeth are now 10 billion times harder to dissolve.

So you are basically telling us that if someone drank the piss of any Finnish, it would be more cleaner that any other countries/towns tap water?Gawwad wrote:

I believe that constitutes insoluble in chemical terms, But your correct that F- and H+ react to form HF (Hydroflouric acid), which is much less soluble than pure H+ ions. (ironically, HF can also etch glass in high concentrations, so keep an eye on your dishes)
My one concern would be Flourine's tendency to attack carbon-hydrogen bonds, which make up the majority of your body (but i believe that the concentration in water is <.002%, so probably not much happening)
Well, NYC only has some chlorine in its water.
Natural filtration FTW.

Yes, sorry, 10^-60. With the F and H thing, I actually meant it displaces an H atom part of calcium hypaxate, but yes, go chemistry!S.Lythberg wrote:

Or are you saying Sydney's is worse? Remember, they had the contamination in their water not too long ago, and the water had to be boiled. Melbourne's water is actually pretty good. If you don't believe me, go to Ballarat/Bendigo. If things haven't changed, they don't even remove all the chlorine in it! Now that's pool cleaner.
