German to English translations [PRO]
Tech/Engineering / ozonization
German term or phrase: Auflösung
From a description of an ozonizing process/system:

I found 'dissolution' and 'decomposition' as possibilities for Auflösung but am not sure which to prefer.

Ozone is highly unstable and must be generated on site. Its oxidation potential (-2.07V) is greater than that of hypochlorite acid
(-1.49V) or chlorine (-1.36V), The latter agents being widely used in water treatment practice. Ozone is thought to decompose
accordingly (Miller 1978, 167-168):

dissolution


Explanation:
Oxygen can't decompose; it is already a singular element. However it can, under certain circumstances, dissolve (like CO2 in a bottle of Coke -- you could just as well use O2 instead).

If your choice is between dissolve and decompose (abbauen, zerfallen), I'd go with the former, although I'm not familiar with the technology your text describes.

I have found several Web pages which talk about the \"decomposition\" of oxygen. Webster, however, offers \"decomposition\" as a synonym for one of the meanings of \"dissolve\" (to dissociate into component parts); hence \"dissolve/dissolution\" covers both eventualities, and therefore \"can\'t\" be incorrect.

  -> Thanks, Kathi. I'm not conversant with the technology, so I'm still unsure.
disagree  Karlo Heppner: Wenn Gillian Recht hat,dann kann sich auch Sauerstoff zersetzen (decompose). Also meine Wahl.

Explanation:
There isn't enough info to decide which of the answers is correct.

At which stage in the process does this "Auflösung" occur?

Decomposition could be correct (O2 can be made to decompose to O radicals, which react with O2 to give ozone O3, i.e. O2 + O gives O3), and if this is an ozoning process (water treatment facility?) O3 will decompose during the treatment.

However, O2 and O3 can both dissolve (in the water?) before they react with whatever.

Re Edward\'s last comment:

Some solids do indeed decompose when they dissolve e.g NaCO3 in an acid (2H+ + CO3(2-) gives H2O and CO2), but this is moderately rare. Most ionic substances simply separate into their ions when they dissolve, this is NOT decomposition in the technical sense, although a layman might think so.

As you may have noticed, I\'m a chemist!

John:
if the whole thing is taking place in the gas phase, you definately have decomposition. In the liquid phase, well it is still a toss up!
