Formation
Disodium glutamate can be produced by neutralizing glutamic acid with two molar equivalents of sodium hydroxide (NaOH).
gollark: Yes.
gollark: You could use `peripheral.getType(name)` to check for the existence of a peripheral. Also to help with finding peripherals by type.
gollark: Primarily Otiose Transformative Advanced Technology, Or Something.
gollark: PotatOS probably leans too far away from the Rust side of things, because half the potatOS PotatoAPI™ has no error checking at all.
gollark: Yes, I know, and it's not any particular errors, just that I have to muck with error types and `?` and `map_err` everywhere.
