It's found in many places, including car batteries, mineral processing plants, petrochemical plants, water treatment plants, etc.t is a very corrosive acid and is a 1 or so on the pH scale which is very acidic. I have tested and concentrated sulfuric acid melted through a r â¦ ag folded twice. - - - - - Sulfuric acid is a strong acid, but an acid being strong or weak doesn't refer to its corrosiveness.
