Magnesium is an active metal if it occurs as a chloride in nature, which method of reduction is suitable for its extraction? |
|
Answer» The method of reduction which is useful for chloride of magnesium which is active is electrolytic reduction. Fused MgCl2 is electrolysed with steel cathode (-) and graphite anode (+). The metal (Mg) will be deposited at cathode and chlorine gas liberates at the anode. At cathode : Mg2+ + 2 e- → Mg At anode : 2 Cl- → Cl2 + 2e- |
