You know that metals can be separated from molten compounds of metals by electrolysis. Find out how metals like Na, Ca and Mg are extracted. |

Answer» Na Produced by the electrolysis of molten NaCl. KCl is added to reduce the melting point of NaCl. Chemical equation: NaCl → Na++Cl At cathode : Na+ + le- → Na At anode : 2Cl- → Cl2 + 2e- Ca: Mixture of CaCl2 and 16% CaF2 are melted and undergo electrolysis. Mg: By the electrolysis of molten mixture of camalite (KCl.MgCl2 .6H2O) and NaCl in equal amounts. |
