Chemistry Jokes and Riddles - Humor for Chemists
A simple equation that describes a relationship between the buffer capacity and for homogeneous pH buffers (particularly for the mixtures of conjugate acids. The pH of solutions is an important chemical property. Oxygen is much more electronegative than hydrogen. Both shared electrons in an oxygen-to-hydrogen . Acidity and basicity, proton concentration, the pH scale, and buffers. Even if you’ve never set foot in a chemistry lab, chances are you know a thing or two about acids and bases. An acidic solution has a high concentration of hydrogen ions (H+^++), greater than that of pure.
So if we look at this, we can derive a couple relationships. So let's go ahead and look at all the possible scenarios for these three things.
So anything to the zeroth power is equal to one. Which tells us that this ratio is equal to one. And if A minus concentration over HA concentration is equal to one, that means that they have the same concentration. I forgot a minus sign there.
This is a really helpful thing to remember.
Acids, bases, pH, and buffers
And this comes up a lot not just when you're talking about buffers by themselves, but also when you're doing titrations. And the point in your titration where the HA is equal to A minus is called the half-equivalence point. And if you haven't learnt about buffers, that's okay. Oh, sorry, if you haven't learn about titrations yet, that's fully fine.
Just ignore what I just said laughsbut if you have, the moral is just that, this is a really, really important relationship that is really helpful to remember. And I said really a lot there. And when you raise 10 to a positive number, when you raise 10 to a positive number, you get a ratio that is greater than one.
So if our ratio A minus over HA is greater than one, that tells us that A minus, the numerator, is actually greater than the denominator, HA. And that means that our ratio, A minus over HA, is actually less than one. So that tells us that our denominator, HA, is actually bigger than our numerator. It's very easy to derive.

Never lick the spoon! Helium walks into a bar, The bar tender says "We don't serve noble gasses in here. Silver walks up to Gold in a bar and says, "AU, get outta here! The first one says "I think I'll have an H2O. What did the scientist say when he found 2 isotopes of helium?
Why was the mole of oxygen molecules excited when he walked out of the singles bar? He got Avogadro's number! A proton and a neutron are walking down the street. The proton says, "Wait, I dropped an electron help me look for it. The proposed name is: As an ion chromatography chemist I made this one up: Anions aren't negative, they're just misunderstood.
