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.

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.

I was on the abutment.

Failure is simply a few errors in judgment, repeated every day.

I do intelligent roles. I don't want to be labeled as doing silly movies. I'm more mature than kids my age because I'm constantly surrounded by adults.

I was one of those guys, you know, playing and singing, and there was no reason for me to write a song, because there were so many beautiful songs out. And Bob Dylan was always the ultimate songwriter, and nobody could ever write a song as good as him, and nobody ever has written a song as good as him.

I enjoy fighting. It's one of my favorite things to do in the world, so I'm just enjoying every minute of it.

The difference between our decadence and the Russians is that while theirs is brutal, ours is apathetic.

The last three or four reps is what makes the muscle grow. This area of pain divides the champion from someone else who is not a champion.

I think I'm a character actress at heart, and I think my work is character work for the most part. I'm not the lead of any films - which is not to say that I wouldn't ever want to be; it is just to say that hasn't been my path.

I always just wanted to write and maybe direct. I'm really only interested in that. And yet the business that I'm in has forced me into being a salesman - that's the last thing that 17-year-old me would imagine I'd end up being. I'm uncomfortable trying to sell anything, but that's what you're doing every time you walk into a pitch.

When Texans suffered from the collapse of the oil market in the 1980s, they could rely on the fiscal union to help them. When Texas boomed with rising oil prices in the 2000s, it contributed to the union to help harder hit regions.

You have to, in some ways, trust in the human spirit and in human ingenuity.

The Obama administration has issued numerous orders essentially suspending deportations, prompting a major spike in illegal crossings.

And I'm working at trying to find a kind of language where I won't be so easily modulated by expectation.

Good arms are overrated.

If you want to fight the evil you see in finance and industry, get to work reading the corporate filings, see if there has been fraud, and where you find it, report it to the SEC or write about it or blog about it.

Trust, but verify.

I was in the U.S. about 15 years. Especially in New York. And then I came back to Japan.

I'm only at the beginning of my career, but I feel successful in that I haven't sold out in any way, shape or form. I feel good about the choices I've made, and I don't feel like I've let go of any of my values.

I don't want to read a book that's depressing.

Milk without fat is like nonalcoholic Scotch.

And also, more and more businesses really want to do the right thing. They feel better about themselves, their workers feel better, and so do their customers. I think this is equally true in the transnational corporations, but it is harder to express in those situations.

Being me right now is sort of amazing.

The biggest difference in writing a sequel is that now there are expectations. But also - and this is the awesome part - now there are fans, too!

Historically, WordPress has been purely focused on the writing side. However, we're thinking about mobile completely differently, and I think there's a big opportunity to take the community of creators that loves WordPress and deliver an audience to the amazing things they're making.
