Chrysocolla and Gibbsite Chemical Formula
While comparing Chrysocolla and Gibbsite 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 Chrysocolla and Gibbsite chemical formula.
- Chemical formula of Chrysocolla- Cu2H2Si2O5(OH)4
- Chemical formula of Gibbsite- Al(OH)3
Chrysocolla and Gibbsite Specific Gravity
Another important criteria for qualitative analysis of gemstones is Chrysocolla and Gibbsite Specific gravity. Specific gravity is the relative density of a gemstone compared with respect to density of water. Gemologists use Chrysocolla and Gibbsite Optical Properties during the identification of gemstone. Specific gravity of Chrysocolla is 2.35 whereas that of Gibbsite is 2.35.
