    I proper hood is important. I worked outside once with hydrofluoric acid - it worked fine until the light breeze I was working in switched directions and I got a nose full of HF vapours. I don't recommend doing that.

The pink solid which separated was collected and crystallised from water, from which it separated only on stirring in a somewhat floculent form. (Found, N= 8,42. Calc., N= 8,39 per cent). ...
