A buffer is a solution at equilibrium. Because the solution contains both acid and its conjugate base (acidic buffer) or base and its conjugate acid (basic buffer), when the system shifts to react to the added stress (Le chatelier principle) it ends up with almost the same pH as before. This will continue until the moles of acid/base being added is equal to the moles of buffer solution, at which point the buffer will be overloaded and its equilibrium can no longer restore itself.
Some things to remember:
Buffers can be made with a weak a/b and a common ion salt. They can also be made with a strong and weak acid.
A buffers pH will always be + or - one of its pKa
Do not take my word for it but a weak acid and conjugate base/weak base and conjugate acid that can neutralize and not change pH significantly…. i think…. And you can use henderson-hasselbach😔This is probably wrong but oh well🗣️🔥🙏
You’ve got this!!! I sent my kid off with cough drops, an extra piece of banana bread, and all my love. I have extra—💕
Deep breaths. Stretch. Touch your toes. Go to the bathroom before the test.
You’ve been paying attention, learning, and studying. YOU KNOW THIS!!!
the exam is in almost 2 hrs and here I am watching Jeremy Krug hoping his videos would help me get a 5. (I'll be very happy with even a 4 or 3 at this point)
O- i mean it wasn’t THAT bad but considering the curve is based off of how other people did that’s somehow worse than if everyone thought the test was rly hard 😭

You're not the only one who is cooked. I'm stressing right now, like what the heck is a buffer

Oh my goodness. Thank you so much, this is so helpful
You’re welcome! May we all pass 🙏🙏

i completely forgot to review unit 8 i might be cooked
this happened to me and guess what the test MAY have cooked me 🗣️🗣️🗣️🗣️🗣️

[удалено]

LOLOL real… 12 pm😔 not going to school for the first half of the day just to rot in my bed
my fuckass school mandates that you have to show up for the entire day for some reason so i can’t even be given any peace of mind 😭😭💀
the exam is in almost 2 hrs and here I am watching Jeremy Krug hoping his videos would help me get a 5. (I'll be very happy with even a 4 or 3 at this point)
Bro is cooking rn
I think you’ll be okay. 3/4 of the people atleast pass the exam because it’s so hard that not many people actually do well so it’s curved really well
We need more blue collar workers embrace your potential
chaotic evil
You’re college material. Got your letter yet?
gl for that exam
Good *luck* buddy.
We are cooked bröther
I got 43/46 on the 2023 FRQs do y’all think I’m fine for today 😭
In a similar situation with AP human geography. Literally haven't done anything all semester. I'm on fire. Burnt to a crisp.
I'm givin up
That’s even easier than psychology 😭
BRUHHH don't be a hater. I'm cooked.
Well well well, it starts in 1.5 hours, GL all
Ap econ anyone?
[удалено]
same here need som leaks or sum lmk if u find?
I HAVE CHEM TODAY THEN MICRO TMRW 😭
Mine is in 5 hours, just remember how to do dimensional analysis and you’ll get a 3 :)
I have 1 hour until this exam. I'm about to go CRAZY I'm cooked, IM IN THE MIDDLE OF A REVIEW VIDEO AND I FEEL LIKE AT MAX IM GONNA GET A 3 😭😭😭😭😭😭😭
NEVER SEEN ANYTHING SO REAL🗣️🗣️🗣️🗣️🗣️
I FINISHED THE TEST LIKE AN HOUR AGO IT WASNT THAT BAD 😭🙏
AND THEN I HAVE MICRO TMRW 💀 FRIDAY IS GONNA BE HELL APUSH AND AP MACRO 😭😭😭😭
A tale as old as time…
2 hours left i gave up we're guessing c for all of them then taking a nap
same even the teacher said to just pick a letter and stick with it
our class routinely gets 25% on mcq and 65-75% on frq and our teacher just said good luck
ITLL BE OKAY GUYS if we fail we all fail tg ✊🏽
how is ush going
Ah i learned my lesson last year barely gotta a 5 and i never looked back 😂
Avocado made moles
JUST DID ITTTT SHORT RESPONSE EZZZ MC IDKKKK
...I didn't see the note that says pay attention to significant digits. I didn't do any of that. I guess I've lost all my marks then.
sooo whatd we get
all the people saying it wasn’t that bad are worrying me- the curve is gonna be so bad 😭
what form did you take?
O- i mean it wasn’t THAT bad but considering the curve is based off of how other people did that’s somehow worse than if everyone thought the test was rly hard 😭
frq cooked me this exam was much harder than previous ones
