Alunite and Copper Chemical Formula

While comparing Alunite and Copper 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 Alunite and Copper chemical formula.

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

Alunite and Copper Specific Gravity

Another important criteria for qualitative analysis of gemstones is Alunite and Copper Specific gravity. Specific gravity is the relative density of a gemstone compared with respect to density of water. Gemologists use Alunite and Copper Optical Properties during the identification of gemstone. Specific gravity of Alunite is Not Available whereas that of Copper is Not Available.
