Question: Sodium is made by the elctrolysis of a molten mixture of about 40% NaCl and 60% $CaC{{l}_{2}}$ because

1) $CaC{{l}_{2}}$ helps in conduction of electricity

2) This mixture has a lower melting point than NaCl

3) $C{{a}^{++}}$ can displace Na from NaCl

4) $C{{a}^{++}}$ can reduce NaCl to Na
