guess the metal (and solvent for bonus arylpoints) 👇
@aryl it's certainly not as obscure as, idk, the neptunium and technetium chemistry I was watching a video on the other day.
But outside of humidity indicators cobalt isn't a metal i work with super often.
Gonna make up some anhydrous salt at some point? Make your own color indicating desiccant? Or what's the plan for it
