Arsenic


Arsenic (unrefined arsenic) is a solid substance extracted from natural arsenopyrites.

It exists in two main forms:

a) ordinary, so-called "metallic" arsenic, in the form of brilliant steel-colored crystals, brittle, insoluble in water;

b) yellow arsenic, crystalline, fairly unstable.

Arsenic is used in the production of arsenic disulfide, shot, hard bronze and various other alloys (tin, copper, etc.)
