The measurement of sales of popular music starts high relative to the wedding anniversary scale, concentrating on gold and platinum (see gold album).Likewise, credit card companies usually have a "gold card" and a "platinum card" (many formerly had a "silver card" then followed by a "gold card", but due to similarity in appearance between silver and platinum these were often discontinued with ...
Nitratoauric acid, hydrogen tetranitratoaurate, or simply called gold(III) nitrate is a crystalline gold compound that forms the trihydrate, HAu(NO 3) 4 ·3H 2 O or more correctly H 5 O 2 Au(NO 3) 4 ·H 2 O. [3] [2] This compound is an intermediate in the process of extracting gold. [4] In older literature it is also known as aurinitric acid. [5]
Au(III) (referred to as the auric) is a common oxidation state, and is illustrated by gold(III) chloride, Au 2 Cl 6. The gold atom centers in Au(III) complexes, like other d 8 compounds, are typically square planar, with chemical bonds that have both covalent and ionic character. Gold(I,III) chloride is also known, an example of a mixed-valence ...
Gold nugget A selection of precious metal elements; gold, silver, platinum, palladium, copper, ruthenium, rhodium, rhenium, osmium, iridium and mercury. They are labeled and arranged by their location on the periodic table. Precious metals are rare, naturally occurring metallic chemical elements of high economic value.

Gold(III) chloride is the starting point for the chemical synthesis of many other gold compounds. For example, the reaction with potassium cyanide produces the water-soluble complex, K[Au(CN) 4]: [20] AuCl 3 + 4 KCN → K[Au(CN) 4] + 3 KCl. Gold(III) fluoride can be also produced from gold(III) chloride by reacting it with bromine trifluoride. [15]
Gold(III) fluoride, Au F 3, is an orange solid that sublimes at 300 °C. [4] It is a powerful fluorinating agent . It is very sensitive to moisture, yielding gold(III) hydroxide and hydrofluoric acid .
