Question

Name a compound added to molten sodium chloride inorder to lower the melting point of sodium chloride from 801 degree Celsius to 600 degree Celsius .

Answer 1

One common compound that can be added to molten sodium chloride (NaCl) to lower its melting point is **calcium chloride (CaCl₂)**. Calcium chloride is often used in combination with sodium chloride in various applications, including de-icing and lowering the melting point of salt mixtures. By adding calcium chloride, the melting point of the salt mixture can be effectively reduced, allowing it to melt at a lower temperature.
