Somit sind Säuren Protonendonatoren und Basen Protonenakzeptoren.

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

.

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.

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

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.

Every digital video player - RealPlayer, Windows Media Player, Vevo, Hulu, YouTube - all of them had different ways of getting you the video, but it was still always the same series of rectangles. The format never changed.

Pride and vanity, the opposites of humility, can destroy our spiritual health as surely as a debilitating disease can destroy our physical health.

It sort of filtered into their subconscious through motion pictures, but it's an historical secret. This - whatever this is - needs to be studied and, in a kind of definitive way, talked about.

I really don't like going out. I don't like restaurants because I don't like the idea of someone, a waitress, being responsible for my evening. I like seconds, and more, and lots of conversation, and I've always hated the idea that in a restaurant an evening just ends. I find that incredibly depressing.

All significant truths are private truths. As they become public they cease to become truths; they become facts, or at best, part of the public character; or at worst, catchwords.

A vacation should be just long enough that your boss misses you and not long enough for him to discover how well he can get along without you.

The Universe is about maintaining balance not fairness. It is by means of balance that true fairness exists in the Universe.

But in fantasy you can make a complete break and you can put people in a situation where they are confronted with things that they would not confront in the real world.

The irony is, going to work every day became the subject of probably my best poetry.

Individual tribes or, in other words, races or stocks, are the constituent elements of the earliest history.

If you can't stand the heat in the dressing room, get out of the kitchen.

Will they attack us? Yes. Will they smear our backgrounds and distort our records? Undoubtedly. Will they lie about us, harass our families, namecall to try to intimidate us? They will. There's nothing safe about it. But is it worth it? Well, let me ask you. Is freedom worth it? Is America worth it?

It is easy to be inspired by history when you're living in a part of it and allow that to seep into your writing: having said that, a minimalist room with no distractions is often better; the most exciting visions should already be in your head.

I cannot forget the place that I come from. The Congo is much in need.

Passion is what adds so much value to life. And if you think about the things that you do, there's so much juice potential for them if you do it.

I just don't like getting scared, like when people hide and jump out of places. That totally freaks me out. I'm not a fan of it.

The most important thing that parents can teach their children is how to get along without them.

I think Yahoo is a great company, with great assets.

Specifically, my favorite tool in Java is hot code swapping in debug mode, meaning I can edit the code while the game is running and immediately see the results in the running game. This is super great for rapid tweaking.

Human curiosity, the urge to know, is a powerful force and is perhaps the best secret weapon of all in the struggle to unravel the workings of the natural world.

I have the most beautiful daughter in the world and I'm grateful for her.

I have to write in sequence and only in sequence.

In places like Glasgow and Newcastle, audiences have a tradition of being amusingly combative. But they're not trying to ruin the act, they're trying to give you a challenge. It's like a cat playing with a mouse - the cat doesn't want the mouse to die, it wants to keep it alive for its own amusement and to be entertained by its struggle.

There is no pause in life, the moment we pause, we stop living.
