Potassium amide
Potassium amide is an inorganic compound with the chemical formula KNH2, i.e. it is composed of a potassium cation, and the conjugate base of ammonia. Like other alkali metal amides, it is a white solid that hydrolyzes readily.

Production
Potassium amide is produced by the reaction of liquid ammonia with potassium.[1]
gollark: Like how potatOS implements string division.
gollark: Yes. But CC does it differently so it *is* sandboxed that way so we can do fun and ill-advised things.
gollark: CC is also extremely well sandboxed now. So much so that they can safely expose `debug`.
gollark: I'd actually expect OC to be a bit more vulnerable to that now since it uses native Lua instead of Cobalt's Java implementation.
gollark: Sandbox?
