The Finest Green in the Lab?
For Friday afternoon, I thought I'd put up another color post. That's nickel (II) chloride hydrate, and the only time I've used it was in a modified borohydride reduction. But that was a glorious prep, at least until the borohydride went in and everything turned black. Nickel chloride in methanol is as green as it gets - that's another one that I'm going to have just take a photo of sometime.
It's fake-looking, like some sort of dye, especially when you see it in an organic chemistry lab. Green is one of the harder colors for "normal" organic compounds to take on, so a vivid lime-gelatin-mix reaction really stands out. Does anyone have any other candidates?
