  Examples (External sources, not reviewed)

of your hydrogen concentration
Sans unité bien sur.
And so we have more hydrogen concentration.
Donc H augmenterait
A bit more concentration of hydrogen peroxide
Le peroxyde d'hydrogène peut être plus concentré, et devenir, du coup, plus chaud.
So it's the concentration of your hydrogen ions times your concentration of your fluorine ions divided by your concentration of your hydrogen fluoride, or hydrofluoric acid.
Actuellement, il va dans les deux directions C'est une réaction d'équilibre
So people really care about the concentration of hydrogen of your hydrogen ions.
Il s'agit en fait de la concentration en ions hydrogène
Well the pH is just the hydrogen concentration.
Eh bien, le pH est juste la concentration d'hydrogène. Nous avons déjà la concentration d'hydrogène.
Now, the same convention is used on the hydrogen concentration.
La même convention s'applique pour la concentration en hydrogène.
Let's say you get your hydrogen concentration to 10 molar.
Disons que vous obtenez votre hydrogène concentration molaire de 10.
So there's obviously things in the world that change the hydrogen concentration. That change this concentration.
Bref, il y a donc des composés qui vont varier la concentration en H ou en H3O .
It equals the concentration of the products of hydrogen ions times a concentration of the hydroxide ions.
Elle vaut la concentration de chaque produit ions oxonium et ions hydroxyde.
This is obviously a much higher concentration of hydrogen than that.
Ce qui est plus élevé d'un facteur 10000.
When something increases the hydrogen concentration, that is considered an acid.
Donc quand un acide fait augmenter
So you could imagine if you place hydrogen chloride in water, you're going to increase its overall hydrogen concentration.
la solution. Donc si on dissout HCl dans l'eau, on va faire augmenter la concentration en
That's where the hydrogen concentration is equal to 10 to minus 7.
Avec donc une concentration en ions H de 10 7 moles par litre.
We add concentration of hydrogen. So let's say 10 to the minus 3.
Pour arriver à une concentration de 10 3 moles par litre.
The concentration of your hydrogen protons because that's really what they are, or hydrogen ions is 10 to the minus 7 molars.
La concentration en protons ou ions hydrogène, c'est la même chose, vaut 10 7 moles par litre.
So the big take away from this is we care about the hydrogen concentration.
Dans les calculs, on met l'accent sur la concentration en H .
So 0.032. And remember, this is our hydrogen concentration. It's also going to be our concentration of, of course, our fluorine ions.
Alors il y a une charge négative partielle, c'est tenté de dissocier les molécules d'eau
If you like Arrhenius's definition of what an acid is, they increase your hydrogen concentration.
Pour Arrhenius, un acide augmente la concentration en H
And it turns out that an acid is just something that increases the hydrogen concentration.
L'acide est simplement un composé qui augmente la concentration en H
So the hydrogen concentration is now 10 to the minus 3. What's our new pH?
Donc avec une concentration de 10 3 moles par litre, quel est notre pH?
So if we make that simplifying assumption, we've essentially solved four our hydrogen concentration, right?
Maintenant
Now, everything I've done so far this is the Arrhenius definition where an acid increases your hydrogen concentration, a base increases your hydroxide concentration.
Tout ce qui a été fait pour le moment concerne les définitions d'Arrhénius l'acide augmente H , la base fait augmenter HO
The next few videos are all going to revolve around the hydrogen concentration in water, essentially.
Les prochaines vidéos tourneront autour de la concentration en H dans l'eau.
We already have the hydrogen concentration. That's 1 molar, or 1 mole per liter of solution.
C'est 1 molaire, ou 1 mole par litre de solution.
In pure water, the concentration of hydrogen ions, and you could also say that that's the concentration of hydronium ions, or cations, because they're positive.
Car ce sont la même espèce.
Because water by itself will have a hydrogen concentration of 10 to the minus 7 and a hydroxide concentration of 10 to the minus 7.
Parce que l'eau en soi aura une concentration d'hydrogène de 10 puissance moins 7 et une concentration d'hydroxyde de 10 puissance moins 7.
So they defined the pH as equal to the minus log base 10 of your hydrogen concentration.
Et on avait défini le pH comme l'opposé du logarithme de la concentration en H
And then your pH in this circumstance well, you could say, oh, it was the hydrogen concentration.
Et puis votre pH en cette circonstance Eh bien, vous pourriez dire, oh, que c'était la concentration d'hydrogène.
Under normal circumstances this means that the concentration of hydrogen ions in acidic solution can be taken to be equal to the concentration of the acid.
Cas d'un acide fort formula_15 où formula_16 est la concentration en acide en mol L.
I guess on the other side, you could add more hydroxide and then you would have more OH concentration, and maybe a little less hydrogen concentration.
En parallèle, on peut ajouter des ions hydroxyde et OH augmenterait et celle de H diminuerait.
If you put some fluorine in water, it will grab some hydrogen not necessarily a ton of it, but it will grab some hydrogen from the surrounding water and increase the hydroxide concentration. It's increasing the concentration of this thing right here.
Si on met du fluorure dans l'eau, il va prendre des ions hydrogène pas forcément des tonnes, mais il va prendre de l'hydrogène dans l'eau environnante et augmenter la concentration en hydroxide. ça augmente la concentration de cette chose là.
Now let's say we were to do something to the water where the hydrogen concentration were to increase.
Et maintenant agissons sur l'eau pour augmenter la concentration en hydrogène.
And when you increase the hydrogen concentration, when you put an acid into an aqueous solution, you are
la concentration en H3O avec par exemple la dissolution d'un acide en solution aqueuse,
So the pH is going to be equal to the minus log base 10 of our hydrogen concentration.
Si le pH va être égale au moins 10 base d'ouvrir une session notre concentration d'hydrogène.
You don't know what the hydrogen concentration is, but you know that when you throw a bunch of this stuff, it's going to sop up a bunch of hydrogen and the hydrogen is going to go down a lot.
Vous ne savez pas quelle est la concentration en hydrogène, mais vous savez que lorsque vous jetez un bouquet de ce genre de choses, c'est passe au mode opératoire normalisé inventé un tas de l'hydrogène et l'hydrogène est vous allez pour descendre beaucoup.
In the Arrhenius definition because it is increasing the hydrogen concentration in the water. It's an acid in the Bronsted Lowry definition because this thing is donating these hydrogen protons.
C'est fort parce qu'il dissocie complètement dans
And by moving gradually up the slope, gradually increasing the concentration of hydrogen peroxide, we can end up with
Et en continuant à évoluer de cette manière, petit à petit, la concentration du peroxyde d'hydrogène s'intensifie, et on peut se retrouver avec ça.
So the lower the pH, the more acidic you have, or the higher concentration of hydrogen protons you have.
Donc plus le pH est bas, plus la solution est acide et plus la concentration en H3O est grande.
So the equilibrium constant is equal to the concentration of hydrogen is 10 to the minus 7 times a concentration of hydroxide is also 10 to the minus 7.
La concentration en ions oxonium est de 10 7, que je multiplie par 10 7 qui est la concentration en ions OH
So once I'm in equilibrium, I'll have my concentration of hydrogen fluoride will be 1.5 molar minus x. And what's my concentration of hydrogen? Well, if x molar, or x moles of this, the way you can view, disassociate, then we have x moles or x molar of that.
Alors, hydrogène aime former des liaisons
(1922) Stratification and Hydrogen ion concentration of the soil in relation to leaching and plant succession with special reference to woodlands.
(1922) Stratification and Hydrogen ion concentration of the soil in relation to leaching and plant succession with special reference to woodlands.
So you're going to have the hydrogen concentration here in the aqueous solution is going to be equal to 1 molar.
Si vous allez avoir ici la concentration en hydrogène dans la solution aqueuse va être égale à 1 molaire.
Hydrogen iodide. Hydrogen Iodide.
L'iodure d'hydrogène de formule HI.
A pH meter is an electronic device used for measuring the pH which is either the concentration of Hydrogen ions in an aqueous solution or the activity of the Hydrogen ions in an aqueous solution.
Un pH mètre est un appareil, souvent électronique, permettant la mesure du pH d'une solution.
