Last time we started our discussion about sodium, and tonight we shall continue it. We have pretty much covered the quantum mechanical part and the properties and uses of elemental sodium, so tonight we shall focus on some of the compounds of that element.
Sodium compounds are extremely common and widespread, but not universally distributed. This is important for reasons to be seen later.
The most common sodium compound is common salt, or sodium chloride, NaCl. Everyone has personal experience with salt, both as a nutrient and as a melting aid for icy surfaces.
