Figure 1.1 TRONA
By running different physical and chemical tests I identified this mineral as TRONA. Chemistry: Na3(HCO3)(CO3) - 2H2O , Hydrated Sodium Bicarbonate Carbonate. Class: Carbonates I have listed the physical and chemical evidence which I have tested in the lab using the provided facilities. Physical evidence:
1. Color: I observed that it is gray, colorless, white, pale brown or yellowish. 2. Luster: the luster is vitreous.
3. Transparency: it’s crystals are transparent to translucent. 4. Crystal System: it is monoclinic; 2/m.
5. Crystal Habits: include prismatic to blocky crystals, but usually massive, fibrous or columnar. 6. Cleavage: is perfect in one direction and poor in two others. 7. Fracture: is subconchoidal to uneven.
8. Hardness: is 2.5 - 3.
9. Specific Gravity: is 2.1 (well below average)
10. Streak: is white.
Calculated evidence of Trona:
1. Electron Density: Bulk Density (Electron Density)=2.15 gm/cc note: Specific Gravity of Trona =2.13 gm/cc. 2. Fermion Index: Fermion Index = 0.0014442381 Boson Index = 0.9985557619 3. Photoelectric: PETrona = 0.67 barns/electron U=PETrona x rElectron Density= 1.45 barns/cc. 4. Radioactivity: GRapi = 0 (Gamma Ray American Petroleum Institute Units) Trona is Not Radioactive Optical evidence of Trona:
1. Gladstone-Dale: CI meas=...
