We've posted quite a few stories about arsenic over the past twenty years here at Neatorama because there are so many things to say about the historic poison. However, you might not have been reading this blog that long, so Neil Bradbury put together a TED-Ed overview giving a brief history of the element and its, uh, "traditional" use in dispatching rivals, wealthy ancestors, and inconvenient spouses. Hence the nickname "Inheritance Powder." That doesn't happen as much these days, or at least we hope it doesn't, because modern chemistry used in an autopsy can detect not only the presence of arsenic, but the amount and the day it was ingested. Arsenic is colorless, odorless, and throughout most of history was undetectable, but it still has legitimate uses in chemistry and industry. There are a lot of stories in this video that you can read more about in our previous posts, going back to 2007.
