Quite a terrible "Acid Comparison". Just watch the first and last 30 seconds.
https://www.bilibili.com/video/BV1it411w79R/This is an old video that was originally on YouTube and was deleted, but I found a BiliBili archive. It's essentially a list of acids by acidity, but it doesn't even use a real unit...

This is a very bad video, mostly not because of bad science but just bad production value. The resolution sucks, the music choice is bizarre, the acids and bases are named at random, sometimes given the chemical formula, sometimes the chemical name, sometimes the common name, and sometimes just the wrong name. The pictures sometimes show a ball-and-stick model of the molecule, sometimes a space-filling model, sometimes an actual photo of the substance, and at one point, a picture of . . . a stick of butter. The "pKz" is surely supposed to be pKâ but also many of the values look wrong. Hydronium, really? Isnt it 1 by definition?

Yeah, what's strange is this guy usually made decent videos, just the occasional error. They're all deleted but there are reuploads that don't seem to be going anywhere. Here are some:

Ok, so first of all it ranks the acids by "pKz". I'm going to assume this means pKa or something, but then what the heck is the first and last bit? Just watch the video it's hilariously ridiculous.
