Sodium metal can be obtained by electrolysis from molten mixture of sodium chloride and calcium chloride in Down's cell. The metal can not be obtained by electrolysis from aqueous solution, because hydrogen will evolve instead.
The atomic ratio between sodium and chlorine in sodium chloride is 1:1, as indicated by its formula NaCl. If the mass ratio is wanted, it is that of the atomic weights of the two elements.
No, they are not the same thing. Elemental sodium (Na) is a bad smelling yellow solid that violently burns up when water touches it. Sodium Chloride (NaCl) is the scientific name for table salt - the...
Sodium chloride (NaCl) is a crystal lattice structure at a molecular level, while sodium itself (Na) is a pure element and also metallic. A pure element in it's natural state will usually have...
