Question
NaCl and CaCl2 are added to fused MgCl2 in the electrolysis of MgCl2 since :
Options
A.melting point is decreased and conductivity is increased.
B.melting point is increased and conductivity is decreased.
C.melting point and conductivity both are decreased.
D.melting point and conductivity both are increased.
Solution
NaCl and CaCl2 both being ionic compounds ionise to give ions which lowers the melting point and increase the conductivity of the mixture.
