Also, where was copper first found and what are its dangerous properties?Sources would be great but not necessary.
Copper dissolves in oxdising acids e.g. nitric acid or acids with oxygen i.e. hydrochloric and sulfuric with air bubbled thru. Also dissolves (Reacts) with ammonia solution and amines. Copper is not particularly dangerous but is toxic at certain concentrations ( as is everything) it is however, an essentialy nutrient for plant and animal life.
