What is ozone (water)?

Question

:P No, I don't mean this thing floating around earth blabla global warming blabla hole..

I mean, when you have bottled water and the ingredients are: "Fresh spring water, ozone"

How do they put ozone in water?

Answer 1

ozone is O3 water is H20...

Answer 2

The ozone (which is highly poisonous) is long gone before you open the bottle.  It is added in very small amounts to make sure other trace impurities are destroyed.  Any ozone left over will decompose to give oxygen.  I would wonder, though, why they need to add it.  Are they getting their water out of the Cuyahoga River or something?

Answer 3

The same way that they put carbon dioxide in soda to make it 'fizz'.

Most any gas will dissolve in a liquid.  The more pressure you add, the more gas will dissolve (Henry's Law).

Answer 4

Ozone is produced using the silent electrical discharge. That is, when an AC voltage exceeding the breakdown strength of oxygen gas is applied, current flows rapidly, and the energy given off can induce the dissociation of dioxygen molecules:

O2 -----> 2O

When an oxygen atom collides with an oxygen molecule, an ozone molecule (O3) can be produced:

O + O2 -----> O3

As a result, a low concentration of ozone is obtained in oxygen. This gas is then bubbled into water. (Of course, this ozone is the same as that of the "ozone layer".)

Ozone is a very strong oxidizing agent that kills all germs present in the water. It doesn't harm us because it decomposes back to oxygen,

2O3 -----> 3O2

with a half-life of about 6 hours. Bottling occurs soon after the ozone treatment, so that no new germs can get in.
