Safety data for sulfuric acid (dilute)

Safety data for sulfuric acid (dilute) 



General 
  Synonyms: oil of vitriol, mattling acid, vitriol, battery acid, dipping acid, 
  electrolyte acid, vitriol brown oil 
  Molecular formula: H2SO4 
  CAS No: 7664-93-9 
  EC No: 231-639-5 
  EC index No: 016-020-00-8 
Physical data
  Appearance: Colourless liquid 
  Melting point: close to 0 C (depends upon concentration) 
  Boiling point: close to 100 C (depends on concentration) 
  Specific gravity: 
  Vapour pressure: 
  Flash point: 
  Explosion limits: 
  Autoignition temperature: 
  Water solubility: miscible in all proportions 
Stability
  Stable. Substances to be avoided include most common metals, organic 
  materials, strong reducing agents, bases, strong oxidising agents. Reaction 
  with many metals is rapid or violent, and generates hydrogen (flammable, 
  explosion hazard). 
Toxicology
  Corrosive, the more concentrated solutions can cause serious burns to the 
  mouth, eyes and skin. Toxic. Harmful by ingestion and through skin contact.
