Wikipedia, Jan. 28, 2013 (Perchloric acid is an inorganic compound with the formula HClO₄. Usually found as an aqueous solution, this colorless compound is a stronger acid than sulfuric and nitric acids. It is a powerful oxidizer, but its aqueous solutions up to approximately 70% are generally safe, only showing strong acid features and no oxidizing properties. Perchloric acid is useful for preparing perchlorate salts, especially ammonium perchlorate, an important rocket fuel. Overall, perchloric acid is dangerously corrosive and readily forms potentially explosive mixtures. Other names: Hyperchloric acid)
