Description
Acids may be solid, liquid or gaseous, and are usually classified as Inorganic or Mineral Acids and Organic Acids.
Generally speaking all mineral acids are more or less corrosive, as are many organic acids. Some organic acids are completely harmless. Corrosive acids are those which readily attack other substances, especially metal and timber, and will cause considerable damage should leakage occur. Such acids should never be handled as they are also corrosive to skin and other human tissue. Poisonous acids are those which are poisonous in themselves or evolve poisonous fumes, which are a danger to life.
