Sulfuric Acid ENVIRONMENT SAFETY HEALTH AND
Concentrated sulfuric acid is a strong oxidant and reacts violently with combustible and reducing materials. The substance is a strong acid it reacts violently with bases and is corrosive to most common metals forming a flammable/explosive hydrogen gas. Sulfuric acid reacts violently with water and organic materials with evolution of heat.
