  History
  
  Scheele's Green
  In 1775, Swedish chemist, Carl Wilhelm Scheele discovered arsenic. Scheele prepared copper arsenite, which has a brilliant green color that was popularly used as a pigment.
  
  
  
  
  
  
  
  
  
  
  
  
  
  
  
  
  
  
  
  
  
  
  
  
  
  
  
  
  
  
  
  
  Chemistry
  
  Chlorinated water converts arsenic to arsenous acid. Adding metallic zinc and heating the acid mixture produces arsine gas. When the gas comes into contact with a cold vessel, arsenic collects.
  In 1821, arsenic was found in the stomach and urine of poisoned individuals. Today, it is common to collecting samples from: blood, urine, stomach contents, liver, vitreous humor, hair, and insects to detect poison.
