Question:
Sodium is made by the electrolysis of a molten mixture of about 40% NaCl and 60% $CaCl_2$ because
Sodium is made by the electrolysis of a molten mixture of about 40% NaCl and 60% $CaCl_2$ because
Updated On: May 2, 2024
- $Ca^{2+}$ can reduce NaCl to Na
- $Ca^{2+}$ can displace Na from NaCl
- $CaCl_2$ helps in conduction of electricity
- this mixture has a lower melting point than NaCl
Hide Solution
Verified By Collegedunia
The Correct Option is D
Solution and Explanation
The melting point of sodium chloride is high, so to reduce the melting point of NaCl some $CaCl_2$ is added to the electrolytic mixture.
