Sulfuric acid



Sulfuric acid, also spelled Sulphuric acid known by the chemical compound H2SO4, and originally known as the oil of vitroil, is a highly corrosive mineral acid with enough dissolving power to burn the flesh off people. It is recognizable as having a colorless/slightly yellow coloring with a pungent ethereal nature and is soluable with water in all concentrations. Because of it not immediately being recognizable, it is frequently dyed dark brown to alert people of its danger. It can be neutralized if caustic soda is placed over it, and can also produce carbon to transform into a rubbery substance if anything containing table sugar (C12H22O11) is exposed to it.

Usage
The detention camp of Zanzibar Land had various puddles of sulfuric acid spread across the prison facility as well as the secret Metal Gear D hangar. Although their use by the Zanzibar Land personnel was intended to be to ward off the Zanzibar Hamster infestation due to their being pests, the puddles also acted as a huge obstacle for the FOXHOUND agent Solid Snake during his mission into the nation. Using some advice from Master Miller, he used some chocolates in the B1 Zanzibar Land rations to neutralize it.

Behind the scenes
Sulfuric acid was an obstacle in Metal Gear 2: Solid Snake. If the player walks over a non-neutralized sulfuric acid puddle, the character will sink down to nothingness, earning an instant game over.
