Carnallite and Sodalite Chemical Formula
While comparing Carnallite and Sodalite 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 Carnallite and Sodalite chemical formula.
- Chemical formula of Carnallite- KMgCl3•6(H2O)
- Chemical formula of Sodalite- Na8Al6Si6O24Cl2
Carnallite and Sodalite Specific Gravity
Another important criteria for qualitative analysis of gemstones is Carnallite and Sodalite Specific gravity. Specific gravity is the relative density of a gemstone compared with respect to density of water. Gemologists use Carnallite and Sodalite Optical Properties during the identification of gemstone. Specific gravity of Carnallite is 2.15-2.40 whereas that of Sodalite is 2.15-2.40.
