Reagiert eine Säure mit einer Base so neutralisieren sich die beiden Moleküle. Es entsteht ein Salz und MEIST auch Wasser.

Nach Brönsted gehen bei einer Säure-Base-Reaktion immer Protonen (H+) von einer Säure- zu einem Base-Molekül über.

.

Somit sind Säuren Protonendonatoren und Basen Protonenakzeptoren.

Gibt eine Säure ihr Proton ab, entsteht aus ihr die korrespondierende Base, nimmt eine Base ein Proton auf, entsteht aus ihr die korrespondierende Säure.

Moleküle die sowohl als Säure als auch als Base reagieren können, nennt man Ampholyte. Zu ihnen zählen z.B. Wasser und Ammoniak.

Die Neutralisation verläuft exotherm, die freiwerdende Energie nennt man neutralisations Energie.

Säure + Base --> Salz + Wasser + Energie

Um messen zu können, ob eine Lösung sauer, alkalisch oder neutral reagiert, berechnet man den pH-Wert.

Im neutralen Milieu ist die Konzentration der Oxonium-Ionen (H3O+) genauso groß wie die der Hydroxid-Ionen (OH-). In sauren Lösungen ist die Option Oxonium-Ionen-Konzentration größer, in alkalischen kleiner als die der Hydroxid-Ionen-Konzentration.

Der pH-Wert ist laut Definition der negative dekadische Logarithmus des Zahlenwertes der Oxonium-Ionen-Konzentration. Der pOH-Wert ist laut Definition der negative dekadische Logarithmus des Zahlenwertes der Hydroxid-Ionen-Konzentration. pH und pOH-Wert ergeben in der Summe immer 14. pH = -lg c(H3O+)

Auf einer Skala von 0 bis 14 bedeutet ein pH-Wert von 7 neutral, ein pH-Wert kleiner 7 sauer und größer 7 alkalisch.

Salzsäure ist eine wässrige Lösung von HCl; Natronlauge bzw. Kalilauge sind wässrige Lösungen von NaOH bzw. KOH; Kalkwasser bzw. Barytwasser sind wässrige Lösungen von Ca(OH)2 bzw. Na(OH)2.

However, if the religions in essence merely repeat statements from the United Nations Human Rights Declaration, such a Declaration becomes superfluous; an ethic is more than rights.

I never will watch a meet that I don't do well in. I just don't like to.

Working with actors really depends on the actor. Most of the directors I've worked with don't really know how to speak to actors, actually; some of the best directors don't.

My own view is that if you filled every member of the parliamentary Labour party with a truth drug and lashed them to a polygraph lie detector, very, very few of them would support foundation hospitals.

I think I've written about family and things in 'Taipei' which could be considered Asian culture.

Review your work. You will find, if you are honest, that 90% of the trouble is traceable to loafing.

My biggest challenge was to make sure that the songs I did were who I am.

Not many child stars make it out of Hollywood alive or sane, and at any given time there are at least three former ones having very public breakdowns.

While small minds were bragging about their material possessions great minds were busy expanding their assets.

We need to have a better balance between a deliberate strategy and staying open. Because in the end, most of us end up being successful in a career that we never imagined we would be in at the beginning.

I'm basically quite a cheerful person.

I want to be Miss USA or Miss America. I would bring the trophy back to Nebraska. My interests are agriculture and corn. Hey, I'm just riding this train as long as I can. As long as I'm having fun, I'll do it. When it stops being fun, I'll try something else.

I'm not just a doormat. I'm not just being stepped on all over the place. If you look at the bulk of my material, it's about trying to find some strength through that.

Hard conditions of life are indispensable to bringing out the best in human personality.

I was interested in politics very much when I was growing up, and that's what I think I really wanted to be - either a senator, or a Supreme Court Justice, and I always wanted to be a lawyer.

Literature is a textually transmitted disease normally contracted in childhood.

I think it's important to be happy before you can make anybody else happy.

I loved Reece Shearsmith and Steve Pemberton's 'Inside No 9.' The way that they constrained each episode to a single location, then tasked themselves with including completely new characters every week, within a single half-hour.

It is by the goodness of God that in our country we have those three unspeakably precious things freedom of speech freedom of conscience and the prudence never to practice either of them.

Nothing is more dreadful than private duels in America. The two adversaries attack each other like wild beasts. Then it is that they might well covet those wonderful properties of the Indians of the prairies - their quick intelligence, their ingenious cunning, their scent of the enemy.

I had been accepted to film school, but my parents couldn't afford it, and yet they made too much money for me to get a scholarship.

Ask, give thanks, repeat. Ask, give thanks, repeat.

Certain people in life are just going to take what's given to them, and certain people in life know they want better and they're going to go find better. I've always been that type of person.

In the university library, we know when a book has been used in a class or put on reserve... or while it was out, did somebody call it back in. It turns out to be a pretty good indicator of how relevant the work is at that time.
