We are getting back into the definition of “salt”. Salt is not just NaCl. “Salt” is an ionic compound made up of a metal and a non-metal ion joined together. It could be sodium chloride, it could be potassium chloride, it could be potassium iodide, it could be any number of combinations. The differences between regular table salt, sea salt, and Pink Himalayan salt is the places it came from and the processing of the material. Table salt has been chemically refined to be about 98% sodium chloride. Sea Salt and PH salt are not as refined. They are taken either out of the water or out of the ground and used. The majority of these are still sodium chloride, though the percentages may vary quite a bit.
