Titanium Extraction Assignment
1 1. TiO2+Cl2-----------------TiCl4+O2 2. Why is an atmosphere of argon acclimated for this acknowledgment ? The titanium (iv) chloride is added to a reactor in which actual authentic sodium has been acrimonious to about 5500c -everything actuality beneath an innert argon atmosphere. During this acknowledgment the temperature increases to about 10000 c . The acknowledgment is agitated out in an argon atmosphere to anticipate magnessium and sodium from reacting with oxygen in the air. 3. Another gas acclimated instead of argon. ny of the elements in accumulation O of the alternate table including helium ,neon,krypton,xenon,and radon which are monoatomic and with bound excemptions chemically innert. 4. Why titanium is an big-ticket metal Titanium is actual big-ticket because it is akward to abstract from ore -for archetype rutile,TiO2 . You cannot use carbon abridgement Titanium can not be extracted by abbreviation the ore application carbon as a bargain abbreviation agent. The botheration is that titanium forms a carbide TiC,if it is acrimonious with carbon,so you dont get the authentic metal that you need. The attendance of the carbide makes the metal actual brittle.
That agency that you accept to use an another abbreviation agent. In the case of titanium,the abbreviation abettor is either sodium or magnessium. Both of these would ofcoarse aboriginal accept to be extracted from their ores by big-ticket processes. 5. The atom abridgement of the action acclimated to abstract titanium. Absolute accumulation of reactants =212g Absolute accumulation of adapted product=22g Atom economy=mass of adapted artefact *100% absolute accumulation of reactants 22*100 =10. 774 212 The absolute abridgement of the Kroll action is 10. 3774 . 6. The atom abridgement will be lower back it was agitated out in an ideal situationwhere all factors are connected and there is no alien arrest but in absolute bearings extal armament like calefaction loss,temparature,impurities will affect the arrangement appropriately a lower value
