Perchloric Acid Use Guideline

General Description

Perchloric acid (HClO4) is a highly reactive, corrosive, powerful oxidizer, which can become unstable and explosive. Its vapors can form shock sensitive perchlorate salts that deposit in portions of exhaust systems. Contact of concentrated perchloric acid solutions with ordinary combustibles such as wood or paper can cause them to ignite, and it reacts vigorously with many organic compounds.
