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

A: The answer is (d): this mixture has a lower melting point than NaCl. When molten salts are subjected to electrolysis, the molten salts are able to conduct electricity. However, NaCl has a very high melting point, making it difficult to use in electrolysis. This is why the mixture of 40% NaCl and 60% CaCl2 is used, as it has a lower melting point, making it easier to dissolve and conduct electricity. This allows the sodium to be electrolysed and released from its compound.
