Tbh a catalyst is a substance that can speed up a chemical process without beeing consumed itselfelbekko wrote:

No excuse that.
Melbourne's water is pretty bad (like drinking pool cleaner), I would hate to think that statement were true.some_random_panda wrote:

Is there more flouride in tap water in the US than Australia? I think I read that somewhere.

most bottled water is tap water, where did you think it came from lol , right out of the stream????loubot wrote:
I don't think bottle water is any better than tap water.

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:
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.
do you mean 10^-60?Vub wrote:
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.

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:

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)
How dare you, ya Victorian!Cheez wrote:
