Question

i) common salt conduct electricity in molten state. ii) why melting point Mgcl2 is high. iii) carbon can not be used as a reducing agent to obtain Mg from Mgo . iv) how is sodium obtain from molten sodium chloride give equation of the reaction.

Answer 1

1) Common salt contains ionic conductivity so for conduction they have to melt in liquid.
2) Magnesium Cloride is a ionic compound so there is ionic bond between mg and cl2 and it is a crystal so structure is fixed so bond can't breaks easily so the melting point of mgcl2 is higher.
