        I was just looking at a 1950s paper at work about how some nutjob made a poly(alkene peroxide) (styrene, I think?), isolated the fucker, and lit it on fire just to see what would happen. those were the days. Nowadays some lawyer with a chemistry minor decides that our hand sanitizer bottles need big red PEROXIDE FORMER labels and 1-year expiration dates (true story, though no longer the case). Now, I’m not saying that we should be allowed to make polyperoxides for the express purpose of lighting them on fire… unless 😳👉👈…?

    Looks like she already went far past the point of equalization? (Unless it’s been too long for me and I don’t remember chemistry).

      Red is acidic, she is droiping the base to reduce the acidity.

      Maybe the usual way is to drip acid into the base (I don’t remember either), in which case a red indicator means she past the point of equalization.

        I remember it being “d-d-d-drop the base” and while you swirled it would get pink but that would disappear, but as it got close, the pink would take longer to disappear, and when you got really close you could even do half drops to try and get the solution to be just the tiniest hint of pale pink. Then you were as close as possible to equalization without overshooting.
