Preparation of a phosphonium ylide for a Wittig olefination.
Triphenyl phosphonium ylides also called Wittig reagents. They are usually prepared from a phosphonium salt, and a strong base such as sodium hydroxide, potassium tert-butylate (as in this case, added on the second gif) or butyllithium.
What happenes here? This:
[Ph3P+CH2R]X− + C4H9Li → Ph3P=CHR + LiX + C4H10
The ylide (Ph3P=CHR) is often a colored compound. In my case it was deep red, almost black, as seen on the above gifs.

PREACHHHH and like basically children here are taught that the biggest reason they wanted to succeed from britain was taxation (basically it all comes back to pride over white greed ew)
lmao Canadian history is so pacified like that too we teach our kids about how there was a "fur trade" between the Aboriginal people and the French and British like there was actually some sort of mutual understanding and respect on both sides like they didn't just come in and ruin everything and strip the indigenous ppl's of all their resources and kill them off in the process
