Im sauren gleicht man mit Oxonium-Ionen H3O+ aus, im Alkalischen mit Hydroxid-Ionen OH-. hin und wieder wird in schmelzen gearbeitet, dann gleicht man mit Oxid-Ionen O2- aus.

1. Atome innerhalb eines Atomverbandes eines Elements haben immer die Oxidationszahl 0. Beispiel: Sauerstoff O2

2. verschiedene Atome: 2.1 Metalle positive OZ 2.2 Fluor F: - I 2 3 Wasserstoff H: + I 2 4 Sauerstoff O: - II 2.5 Halogene: - I

3. Bei Verbindungen ist die Summe der Oxidationszahlen aller Atome 0.

4. Bei Ionen ist die Summe der Oxidationszahlen aller Atome gleich der Ionenladung.

Oxidationszahlen sind eine fiktive Größe, die beim Aufstellen einer Redoxreaktion hilft. Beim bestimmen muss man einige Regeln beachten.

Oxidation ist immer eine Erhöhung der Oxidationszahl eines Elements, Reduktion immer die Reduktion der Oxidationszahl eines Elementes.

Oxidation ist eine Reaktion, bei der Elektronen abgeben werden. Bei einer Reduktion werden Elektronen aufgenommen.

1. Man bestimmt die Oxidationszahlen der beteiligten Verbindungen.

2. Man erstellt Teilgleichungen und bestimmt Oxidation und Reduktion anhand der Änderung der Oxidationszahlen.

3. Man fügt die aufgenommenen oder abgegebenen Elektronen in die Teilgleichung ein.

4. man führt, abhängig vom umgebenden Medium, einen ladungsausgleich durch, so dass auf beiden Seiten der reaktionsgleichung die gleiche Ladung steht. Das muss nicht 0 sein!

5. Man muss mit Wasser H2O einen Stoffausgleich durchführen, sodass links und rechts des Reaktionspfeils die gleiche Summe der Elemente Wasserstoff und Sauerstoff vorliegt.

6. Man kontrolliert die Elektronenbilanz. Es müssen genauso viele Elektronen aufgenommen werden, wie abgegeben wurden. Ist das nicht der Fall, wird ausgeglichen, indem man das kleinste gemeinsame Vielfache der Elektronenzahl sucht und die Teilgleichungen entsprechend multipliziert.

7. Man erstellt eine gesamtgleichung durch Addition der beiden Teilgleichungen. Gleiches wird dabei gekürzt.

Bei organischen Verbindungen wird jedes Kohlenstoff-Atom einzeln betrachtet. Kohlenstoff-Kohlenstoff- Bindungen zählen nicht zur Ermittlung der Oxidationszahl, Wasserstoff hat immer +1, Sauerstoff immer -2. Insgesamt muss das Kohlenstoff-Atom mit seinen Bindungspartnern (außer Kohlenstoff) auf die Summe 0 kommen.

'Niggy Tardust' is the voice of a generation, a generation that does not define itself simply by what it's born into.

I always tell people I'm very large in Uzbekistan.

I got to thinking about the Book of Revelation that was written by a Jewish prophet who was also a follower of Jesus who hated the Roman Empire. I realized that the Book of Revelation could be a way to reflect on the issue of religion's relationship to politics.

I didn't study theology out of piety. I studied it because I wanted to know.

Other than my hundreds of arrests I really don't have that much experience with the law. While the majority of people aren't corrupt, there certainly is an awful lot of corruption in this country.

By very conservative estimates, Turkish repression of Kurds in the 1990s falls in the category of Kosovo. It peaked in the early 1990s; one index is the flight of more than a million Kurds from the countryside to the unofficial Kurdish capital, Diyarbakir, from 1990 to 1994, as the Turkish army was devastating the countryside.

I'm very skeptical about the good intentions of Milosevic.

China is a very brand-intensive society. The reason that brands are so very important is that they are a way to signal social status.

If you're not a makeup artist, and you just try to go for the big looks, it just gets the best of you.

I will tell you this much. God himself comes down with his ribs from Heaven, and he distributes them to the TGI Friday's. And that's how they get them.

We expect forty-year-olds to have grown up at some point, and to be engaged and adult and take responsibility, and doing nothing would seem to go against that.

The wide world is all about you you can fence yourselves in but you cannot for ever fence it out.

Learning to ignore certain people is one of the great paths to inner peace. Life gets easier when you delete those who make it difficult.

Before I go to bed at night, I ice my face, because it closes your pores and makes a difference in the morning.

The decision to kiss for the first time is the most crucial one in any love story.

The melancholy days are come, the saddest of the year, Of wailing winds, and naked woods and meadows brown and sear.

To me, racism is so played out and corny and stupid, especially in music, where you now have Nelly doing songs with Tim McGraw, on the hit single 'Over and Over.' Anyone who thinks about that just needs to get a life.

The lumpiness of 'The Good Lie's progression - from infancy to adulthood, and from ethnic horror to gentle social comedy to a heroic gift of freedom - proclaims the film's respect for facts and truths that can't be squeezed into a smooth narrative.

I have a stab wound on my left hip and one on my thigh and a slash mark across my right calf. I have a bottle stab wound on my left calf.

It's so funny because all those years I was working, I basically always felt that whatever job I was doing would probably be the last one I would get. I really never thought that I stacked up with the other girls.

It's never a done deal until it's a done deal.

I think that humor has become a principle means of communication among Americans about politics.

I mean that the time where we need International agreement more than ever on the environment and the rest, poverty we are breaking up our International Institutions and the rule of law and Tony Blair is part of it.

Dancers, many dancers today can do so much technically. You can give them steps that are complicated, then more complicated, pyrotechnical - and they can execute these steps to perfection. But to do simple steps with a pure classical line, that is truly difficult.
