Why is it very difficult to extract Titanium from its ores?
Reduction of Ti with Carbon produces brittle Titanium Carbide
How is Titanium(IV) Chloride formed from the Titanium Oxide ore?
Reacted with Cl & C TiO₂ + 2Cl₂ + C |> TiCl₄ + 2CO
How is Titanium produced from Titanium(IV) Chloride?
Reduced with Magnesium TiCl₄ + 2Mg |> Ti + 2MgCl₂
Use of Ca(OH)₂ (slaked lime)?
Neutralises Acidic Soils
Test of solubility of group 2 sulfates?
Add Sulfuric acid to solutions of group two ions, observe precipitates
What is the test for sulfates?
Place a small amount of dissolved sample in a test tube Add nitric acid to remove carbonates Add a few drops of BaCl₂ White ppt = SO₄²⁻
What is the test for solubility of Group 2 Hydroxides
Add NaOH(aq) to solutions of the group 2 ions Observe precipitates
