Making Silver Dichromate

From a channel Lumen includes in full: Every sampled upload is a real lab procedure footage of a chemical synthesis, mostly following Vogel or Organic Syntheses, narrated with quantities, apparatus, rationale, mechanism and safety notes. Titles are plain descriptive compound names with no hooks or clickbait. The intent is clearly to show how each preparation is done, and even the terser early videos are purely procedural rather than spectacle.

A 5-minute video from Corrosive Chemistry's catalogue; the title names its topic.
