Question

Sodium is made by the electrolysis of a molten mixture of about 40% NaCl and 60% CaCl2 because (A) Ca2+ can reduce NaCl to Na (B) Ca2+ can displace Na from NaCl (C) CaCl2 helps in conduction of electricity (D) this mixture has a lower melting point than NaCl

Tardigrade Admin · Accepted Answer

The melting point of sodium chloride is high, so to reduce the melting point of NaCl some CaCl2 is added to the electrolytic mixture.

Q. Sodium is made by the electrolysis of a molten mixture of about 40% NaCl and 60% $C a C l_{2}$ because

$C a^{2 +}$ can reduce NaCl to Na

$C a^{2 +}$ can displace Na from NaCl

$C a C l_{2}$ helps in conduction of electricity

this mixture has a lower melting point than NaCl

The melting point of sodium chloride is high, so to reduce the melting point of NaCl some $C a C l_{2}$ is added to the electrolytic mixture.
