Common table salt is odorless, white and cubic in structure. It is hygroscopic, has a melting point of 1,472 degrees Fahrenheit, a boiling point of 2,669 degrees Fahrenheit and a density of 2.165 grams per cubic centimeter. Salt is used as a food additive, an industrial additive and a de-icing agent.Continue Reading
Salt is an ionic compound consisting of sodium and chloride in a face-centered-cubic lattice structure. Salt contains equal portions of chlorine and sodium. Bulk salt crystals are translucent and cubic in shape. Pure salt is white, although impurities may give it a blue or purple tinge.
Salt has a high water solubility of 359 grams per liter. Salt in water solutions can be made to recrystallize as dehydrate sodium chloride, where each sodium chloride molecule is weakly bonded to two water molecules. Adding salt to water changes its physical properties. A salt and water solution has a lower freezing point than just water. As the amount of salt added increases, the freezing point correspondingly decreases until the solubility limit.
Salt used for culinary applications is usually refined to between 97 and 99 percent purity. Additives to table salt include anticaking agents, such as sodium aluminosilicate or magnesium carbonate, which make the salt flow more freely.Learn more about Atoms & Molecules
The alkali metal sodium is used in making table salt as well as baking soda, borax and the sodium lamps that illuminate highways. Potassium is another alkali metal and is used in making fertilizers, inks, matches, dyes and fireworks.Full Answer >
The chemical formula for table salt is NaCl. Also called sodium chloride, natrium chloride or halite, table salt is an ionic compound that contains a positively charged ion of sodium and a negatively charged chloride ion connected through an ionic bond. Table salt appears as a white crystalline powder or colorless, transparent crystals, and it is one of the most commonly used salts.Full Answer >
One example of an ionic bond is table salt, which is the compound sodium chloride. Some other examples of ionic bonds include iron oxide (rust), calcium chloride (rock salt), sodium fluoride (toothpaste fluoride) and sodium hydroxide (lye).Full Answer >
