Hello. I know there are such things as poisonous plants and fungi. Are there any such plants and fungi that are immune t chemicals and acids?
That would be the deadly nightshades, such as potatoes and tomatoes.
I don't remember details, but some plants have the capacity to remove pollutants such as heavy metals and other toxic wastes from contaminated marshland.

Would you like fries with that?
Immune to acids? You mean like a buffer or plants that aren't harmed by acids?
I don't think you'll find any plants that are resistant to strong acids like sulphuric acid, but as far as I know (which quite frankly isn't that much) our blood has a buffer that prevents huge fluxes in pH (strong acids in large quantities would still be harmful), for example when you exercise anaerobically you start producing lactic acid. This would be lethal if it weren't for the pH buffer.
If this is present in humans it's not unlikely that the same functions would be present in plants or fungi. Maybe. As I said I'm no expert.

So nightshade is immune to corrosive and/or caustic substances?

Salt cedar (tamarisk) and salt bush come to mind. The only question left is how to dispose of the polluted plants.
