ELI5: How is corrosive acid stored? How does it not just eat through the container?
gpt
corrosive acid isn't one term that means it'll eat/burn through anything. 

there are mainly two types.  ones that are corrosive to metals and ones that are corrosive to organic materials.  sometimes a particular acid will overlap in metals/organic materials.

so you just use the container that the acid is not corrosive to.
