TIL you can literally drink pure Phosphoric Acid and it wont destroy your mouth. I mean i knew it wasnt the strongest of acids but I didnt realize how weak it was.
I found this out because a vitamin I bought is 95% water and 5% pure phosphoric acid. i put a few drops out and let the water evaporate then licked it and to my surprise it was tart but didnt burn. Should have been close to 85% pure after the bulk of the water evaporated.
