pure gold


Gold(III) chloride, traditionally called auric chloride, is the chemical compound with the formula AuCl3. The Roman numerals in the name indicate that the gold has an oxidation state of +3, which is common for gold in its compounds. .. .
Gold, Au, has long been prized for its beauty, resistance to chemical attack, and workability. Because it occurs as a native metal, has a relatively low melting point (1063 oC.), and is malleable, early man easily separated it from rock and cast or hammered it into beautiful designs. Gold serves as a monetary reserve and is used in jewelry, scientific apparatus, dentistry, and photographic processes.
