Reminded me that in HS chemistry I got to perform an "experiment," in which, following instructions, I mixed some F salt with H2SO4 in a dish, which was covered with a small glass plate that had been coated with paraffin wax, with a design scribed in it. No hood in the classroom, so I put the assembly outside the casement window and left it overnight. The glass plate was etched, as expected. I don't recall, but the residues probably went down the sink.

A quick search says that HF can be used in an alkylating unit 4dog Jan 2024 #3

That was, I think, a potentially very dangerous experiment. Hopefully the "salt" was calcium fluoride. NNadir Jan 2024 #4
