Copper and Alunite Chemical Formula

While comparing Copper and Alunite physical properties, the important data you should know is its chemical composition. Since chemical formula defines the molecular structure of the crystal, most of the physical properties like color, tenacity, solubility are governed by Copper and Alunite chemical formula.

  • Chemical formula of Copper- Cu
  • Chemical formula of Alunite- KAl3(SO4)2(OH)6

Copper and Alunite Specific Gravity

Another important criteria for qualitative analysis of gemstones is Copper and Alunite Specific gravity. Specific gravity is the relative density of a gemstone compared with respect to density of water. Gemologists use Copper and Alunite Optical Properties during the identification of gemstone. Specific gravity of Copper is 2.6-2.9 whereas that of Alunite is 2.6-2.9.
