Acid identification through basic titration using a phenolphthalein indicator.

Fuck it! And the fucking hours it takes to set it up repeat two more times because the final solution was too dark. My burette is rigged to fail at the last minute, I fucking sear!

That is all.

yea, titration is a bitch.

I seemed to have been the only one who mastered it to a precise result every time in my early days of learning.

Worst cases were non working cocks.

One of the few lab techniques where I was actually competent... Four years of university and basically every experiment blew up on me in some way, but the titrations were always fucking perfect. I'm pretty much a titration savant.

You had chickens doing titrations for you?

I just hated that we had to stir the mixtures ourselves rather than having the magnetizing ball in it to mix it for us.

we sat there with a cock in the hole having to swirl the reservoir just to keep it from turning pink.

Speaking of burette failures, how can one un-stick stopcocks? I have about a dozen bits of glassware with sealed stopcocks, including a couple of burettes ... I'd not be happy trying to simply force them.

Depends why they're stuck. If there's shit crystallized in there, you'll need an appropriate solvent bath (i.e. soak the end in water or ethanol). If they're just jammed in because someone was being an idiot, then you'll need to do a lot of very patient twisting... though maybe a bit of solvent will help there, too, if it can penetrate around the sides as you work the cock around in the hole.

I like to swirl manually, because I have an issue with putting balls in my pink.

Thank you kind sir, I have a few solvents at my disposal, hopefully at least one will be of use.

ITT Chemistry innuendos.

Also mfw I never have to do Chemistry again since my A-levels are over
