Imagination is more important than knowledge.
This is the speed I perform all my titrations at.
Fuck titrations
Ah Chem lab 101
DDDDDDDDDROP THE BASE
Where the solution turns pink is locally more basic, but as the entire solution is homogenized again, the pH will drop again.
I taught quant lab and the biggest mistake my students would make on this titration would be that they would call the endpoint when a dark pink color formed, not at first sign of pink, when the solution has the slightest tint of pink.
Why are you wasting so much of that expensive juice
This brings back TA nightmares.
Student: My titration isn’t turning pink!
Me: Did you add the indicator?
Student: The what?
Me: The Phenolphthalein indicator. It’s what makes the solution turn pink as it becomes more basic.
Student: Yes, I added this. *Holds up beaker of base*
Me: No you were supposed to add a drop of this stuff. *Solution turns into peptobismol*
Student: Ohh I thought we were supposed to add that at the end.
Me: *cries internally*
Took me a moment to remember how to pronounce it and what it is lol

I’m suddenly reminded of all my relationships.
Why are you using such a small conical flask? WHY IS IT THAT YOU PUT SO MUCH BASE YET IT DIDN’T EXCEED THE END POINT WHERE IT’S PERMA PINK?
Fuck that shit, we had to get a super light pink in chem class one time and it was the hardest shit I’ve ever done.
Phenolphthalein: It Makes Ya Poop!
Ugh such a basic reaction
Ah the legendary forbidden Kool-Aid
You need a half drop more, donr put a full drop though or ya fucked it up
United Nuclear: Because Sigma Aldrich won’t ship to my house
Did titrations(?) for my 11th grade chemistry final and they are *frustrating*
I always emphasize the second “ph”
This guy titrates.
You haven’t lived until you’ve done +70 titrations in one shift.
One… more… drop…. Fuck!
That shit burnt me lol
Titrations damn it.
The more I try to pronounce this word in my mind the funnier it gets
What chemical is that
Chemistry 2 titration lab PTSD flashbacks
I feel like phenolphthalein is one of the colors Bob Ross painted with.
Edit: changed to painted*. He ded.
Ahhh, flashbacks to high school chemistry.
That name sound like snagglepuss is saying it.
Reminds me of this https://youtu.be/Kln0v_L5ExE
This is what i imagine happens when i drink cream soda
People complaining about no water. Water duplicator right here /s
I had a lab practical once that consisted of a titration. Just as I went to shut the flow, my stopcock fell out of the buret. Have never done a titration since.
Triggered w flashbacks of AP Chem
This is an idiot question but what will happen if a Drop of Blood mixed with Phenolphthalein?
I actually did a titration yesterday, we titrated KHP with NaOH. My data was awful
Fun to say, fun to spell!
